military gun salutes have honoured the duke of edinburgh, who died on friday. buckingham palace announced he'll be laid to rest next saturday in the grounds of windsor castle. because of coronavirus restrictions, his funeral will take place, with no public processions. the palace has said prince harry will attend. prince charles paid tribute to his father saying he gave the most remarkable, devoted service to the queen, his country and the commonwealth. flags have been flying at half—mast as commonwealth and world leaders continue to send condolences to the royalfamily, including the president of china and the pope. thousands of people have been evacuated from the eastern caribbean island of st vincent after a volcano on friday sent a cloud of ash and smoke high into the air. the prime minister said evacuees had been temporarily housed on cruise ships and on safer parts of the island.

now on bbc news, click. it's the hardest problem in technology, and one that could change everything. this week, we're in arizona, the self driving capital of the world, to ride in the latest robotic vehicles. meet the people who are not happy to see them... what am i going to do then? stand in line for food? and to find out what happens when the tech goes wrong. when california told uber that there were going to be some new regulations they need to adhere to,

when california told uber that there were going to be some new regulations they need to adhere to, governor ducey in a public announcement said... california may not want you, we want you to know that arizona does. we are a state that is open for business. we are a state that welcomes business and new people and technology. our governor, governor ducey, had basically opened wide - the arms of our state . to welcome them there and it was a no—brainer. chandler is a hub where - autonomous vehicles are growing and having more miles mapped on our roads than any place - else in the galaxy. it is kind great to be| in the centre of that. chandler, i believe, was chosen because it has very wide streets, it's very clean

streets, they are on a grid. and the people would be very accepting of this kind of technology. and so it was that the technology that will one day change our society, our landscape and our lives, found a home in arizona. the makers of self driving cars have flocked to the town of chandler, which has fast become the industry's test—bed. today, i'm taking a ride on one of the most prolific types of self driving cars here made by google's subsidiary, waymo. now, self driving cars come kitted with loads of sensors so they can see in every direction and sometimes in ways that we can't with our eyes. on top we've got loads of normal cameras looking in every direction. and the fact there's loads of them means they can judge distances by seeing how different objects move in relation to each other. there's also radar, four

of those, one on each corner, and these spinning things are the really interesting things. these are lidar sensors, there are five around and a big one in the black bump on the top, which can see three football pitches ahead and behind. right, let's go for a ride. we have our safety driver. and away we go. please remember to. buckle your seat belt. we have just pulled out in front of quite a fast moving car there. we made it. i'd call that quite a human manoeuvre. companies like waymo are experimenting whether their technology can avoid hitting you. i mean, that's the experiment. when you go out on the streets here, or when you cross at a crosswalk, and there

is a waymo, it is actively testing whether or not its cars can avoid an accident and to avoid an accident with you if you happen to be on the roads. and some people also are clearly offended by that notion. in fact, some residents have reacted very strongly. reporter: check out this video we found on youtube showing l a man attacking a self driving car. you know, there's hundreds of thousands of people that see these cars on the road everyday, but there have been some folks who really don't like them and have either tried to run them off the road with their own cars or thrown rocks at them. one man drew a gun and aimed it at the safety driver as the car passed by his driveway. so some people really have a problem with this amount of technology sharing the roads with them and kind of cruising through their neighbourhoods at all hours of the day. but a lot of these incidents are not when the car cut someone off in traffic, or the things that would maybe make another driver mad at me. it's just their presence, it's just the fact that they are there, that seems to really set people off and you know, in some instances, it's not even people who are driving.

it's people riding their bike or walking that throw a rock at them or run out and slash a tyre whilst one is stopped at a stop sign, so frankly, i can tell you what's going on in their minds, because i would never run out and slash someone's tyre, you know, for no reason. but there is just something deeply offensive about this technology and how ubiquitous it is in this part of arizona. we in the last three years, we responded to about two dozen incidents were people have taken some kind of action against the vehicle or the vehicle and driver, where this could have been what we classify as maybe a road rage, where someone may confront the vehicle and yell at the driver. we have had incidents of criminal damage where people have thrown rocks at the vehicles, we had one particular incident where a person in the neighbourhood actually pointed a gun, pointed a pistol at the vehicle. probably the number—one frustration is that waymo vehicles being safe, being prudent and following the law and there are people who get frustrated by that.

so there are plenty of people in a hurry and plenty of people that go above the speed limit or make improper turns or whatever the violation is, and sometimes, people have been annoyed at the vehicle actually going the speed limit and driving correctly. in chandler there is the same mix of excitement and concern about self driving cars that we have seen everywhere. the difference is, for these people, it's happening right in front of them, right now. it's big money saying, "hey, listen, this is cool, - this is new, i'm surej you would like this," because you see it and it's. fascinating, but at the same time, you are costing - people theirjobs and people who are taken care of their. families, but you'd rather see something cool and be in this new age ratheri than a still care - about the people that actually this affects. and we are lost if you think like that, man. i you are lost. i absolutely would go into self driving vehicle. i mean, i think that it's

such a cool experience. this is something you would see on tv when you were a kid and old 90s movies of self driving cars and the fact that it's actually here and at our fingertips and think it's incredible. lyft drivers are going to lose theirjobs, cab drivers will lose theirjobs are not only will they lose theirjobs, i promise you, they're going to try and figure out a way to make machines create these cars, so they're not even going to let humans create the cars. like, do i trust... trust a machine with my children's lives... - i don't know, that's... i don't know if i- could do that or not. and last year, the fears of the community became a reality. a self driving uber vehicle failed to detect her crossing an empty road at night, and the safety

driver failed to hit the brakes. it was the first case of a pedestrian being killed by a self driving car. the uber was, the vehicle was a volvo again, it was a self driving vehicle. it was in the autonomous mode at the time. and our investigation did not show, at this time, that there was significant signs of the vehicle slowing down. the uber vehicle hit elaine herzberg at 38 miles an hour. this was a huge moment for the burgeoning industry, which led to uber having to immediately halt their self driving programme. so what exactly happened? and whose fault was it? we went to the site of the crash in tempe, arizona with the news editor of the phoenix new times, to find out more about the incident. ok, it's on the other side. she took her bike from this area, walked across this lame, and then entered this lane.

the uber vehicle was in this lane. and itjust kept staying in this lane. even though the pedestrian is here. it should have swerved, it had time and place to swerve, but it didn't. so before she made it to the sidewalk, it impacted her. i absolutely would have seen elaine as she started to cross the road, and i would have absolutely braked for her, most reasonable drivers would have. in fact, any driver who was paying attention would have not hit elaine herzberg. in order to entice uber and other companies into arizona, governor ducey had relaxed regulations, which meant companies faced no requirement to disclose anything about their programmes, including crashes. basically, the governor invited uber in, that was one problem. they were operating here without any real transparency, in terms of what they were actually doing, when the vehicles were in autonomous mode, what their criteria were for it. and then so, the vehicles were doing anything they wanted

tempe police called the crash entirely avoidable, after investigations found that the safety driver was watching television on her phone at the time of the fatal incident. miss vasquez could still face charges of the secular manslaughter. she looked down, they estimate 160 times during the circuit that she was doing, the evidence showed that we she was streaming the view, which is a tv show, on her phone at the exact time of the impact. so what exactly went wrong with uber�*s self driving technology on that night? it can't really be to do with poor visibility, can it? one of the messed up things about this whole accident has been the video that was released by uber after the accident. and if you have seen this video, it looks like the street is very dark and then at last second, the woman on the bike

suddenly pops out of the darkness right before the impact. in fact, this area is not as dark as video shows. this drive—through at night follows the same route as the uber vehicle. it shows that the street lighting makes the route clearly visible, far into the distance. the new york times reported that uber were not living up to expectations before the crash. as of march 2018, uber were struggling to meet their target of 13 miles per intervention in arizona. as a comparison, gm owned cruise reported to california regulators that they went more than 1,200 miles per intervention, and waymo said that their california test cars went on average of nearly 5,600 miles before driver intervention. reports said that the uber vehicle actually detected elaine herzberg six seconds before the crash, but the perception system got confused, classifying her as first an unknown object, then as a vehicle, and finally as a bicycle. those volvos came from

the factory with an accident avoidance system, one of these new set autonomous features that a lot of the new cars have. 1.3 seconds before impact, the self driving system realised emergency braking was needed. however, uber had disabled the emergency braking system on the volvo to prevent conflict with the self driving system. nevertheless, prosecutors have determined that uber were not criminally liable in the death. if uber had not disabled that technology, then potentially the vehicle would have detected the pedestrian, even without the uber autonomous technology. just with the volvo technology, and stopped the vehicle. but uber disconnected that, because apparently the vehicle was being a little too jerky in its motions, and it did notjive correctly with the autonomous vehicle system that uber had in there. a safety driver supervising

an imperfect system should ensure its overall safety. however, that only works if they're paying attention. with self driving cars being tested live on busy streets, accidents are inevitable. so this may not be the last incident that we see on the road to a driverless future. but the number of accidents involving self driving cars is very low for the millions of miles of testing that have taken place. if there's an opportunity to keep our roadways safe, that's certainly our responsibility and our mission to keep our community safe and obviously our roads. so if we can reduce the number of collisions and people being injured and killed, by leveraging new technology, it's something we certainly want to explore and support as moving forward, because we know that overwhelming majority of collisions are preventable, they are caused by humans. we are just not able to share |

in the way that these vehicles are, i don't have access to ten billion driven miles. _ which in the future, - these vehicles will have, every oddity that happened to i be disseminated across a fleet. i want a world where a fender. bender in copenhagen improves someone safety in a mine i in cape town that afternoon. in a way that we just don't as humans. i in 2017, national statistics showed that over 10,000 people were killed because of impaired drivers. over 300,000 people nationally are affected every single day because of impaired driving. two out of three people are going to be affected at some point in their lifetime across this country, and when we think about self driving technology, the reason we're so excited about this is because if we can take that number of 10,000 people, and drop it by one, 9,999 because of this technology, that's what we want and that's what we strive for.

and it's notjust the added safety. there are many people who will be empowered and mobilised by self driving cars. the biggest challenges for people when they think about giving up their keys and getting rid of the car and not driving any more is that loss of independence. so self driving car technology, for people to be a to maintain that dignity and independence to go where they want to go when they want to go, is tremendous. to not have to rely on somebody else, when you start talking about the senior population, that sense of pride and independence is very, very strong. so to try to take that away from somebody is a really difficult situation. we have large communities here where people have come to retire and at some point, they are going to me to turn in those keys. and be off our roads. so that is certainly a force. other people with impairments, whether blindness or things that would keep them from being able to drive. if you have a c—section i

ora hysterectomy, "no, there are just nuts things that are out there. - because we haven't changed how we drive in 100 years. _ it's got to change. it's not ok. let alone the safety stuff. so mobility of people, - the aged, the young, the ill. we want to stay mobile, right? autonomous cars, then, certainly have the power to change lives and save lives when the technology eventually becomes reliable. and when it becomes socially acceptable. butjust over the horizon, there are other vehicles which may be driving themselves about even sooner. trucks are highway vehicles. and when they do stray towards populated areas, it's usually on the outskirts, moving from depot to depot. so unlike autonomous cars, lidar sensors are not the key to these robo rigs.

it's these, long—range cameras. you might recognise we have two lidars on the system, but most importantly for our vehicle, we have a camera array, this primary sensors are cameras because this is a large truck, we need to see a great distance. this vehicle can perceive obstacles at 1,000 metres away, well over half a mile from the vehicle. we also have side facing cameras which are used on surface streets, conducting unprotected left and right turns as a primary sensor. further back, we have cameras that are giving us close surveillance of the lanes around us, that enhances what the lidar is also seeing and we have cameras that are looking behind the vehicle and at the trailer. all of these sensors combined create a long—range vision system for the truck that helps it to detect the object's speed, trajectory and can even work out its intent. at 1,000 metres, an autonomous truck could have up to 35 seconds of reaction time. and if you are expecting

some high—tech controls in the cab... well, you may be surprised. this is probably the most important button in the vehicle. this enables autonomous mode. so, when we reach a point where the vehicle is ready to go autonomous, the button is pressed, and off we go. now, these trucks are not the largest autonomous vehicles being driven in arizona. they have some big competition. mind—bogglingly huge mining vehicles from the likes of cat and komatsu are driving themselves through huge quarries. an autonomous truck needs three systems to drive. perception system consists of radar, lidar on the top, and then a positioning system which is an inner unit measuring unit, gps, tied together by the planning system to drive the truck. the best way to avoid an obstacle is to never get close enough to actually come in contact with it at speed,

so pick it up at a very long range and then verify and correct it at what we calla mid—range, well within stopping distance. so how fast can we going this thing? this truck is capable of going 40 mph. oh, my word. and we are really wanging it round the corners, as well! it's not shy about cornering! once we are loaded it's a whole different track as well. you have 400 tonnes, carrying around. right. and as the vehicle aware that it's loaded and it drives differently? correct. but the trucking and mining industries are huge employers, so self driving technology will inevitably lead to significant job losses. autonomous trucks are safer than human operators, - a couple of reasons why. they don't fatigue, they do exactly what we tell them i to do, and they do it the same way over and over and over. . people is actually a pretty big cost in the economics. - when you think about one truck running continuously for 24 - hours needs 4.5 operators, it's actually quite a large cost. - you have food cost, camp costs, travel costs. -

so when you are flying i in hundreds of thousands of people every single week, that starts to add up. - no—one wants to eliminate a job, we want to find - a different rolei for that person. we just completed a run with the us postal service. it's a 2,100 mile round trip that we executed autonomously. self driving trucks aren't bound by a human driver's hours of service regulations. human drivers can only drive so many hours per day and then they must take a rest break. self driving vehicles will be safer than human drivers. they don't sleep, they don't drink, they don't get distracted. this is a crucial element of autonomy. since there is such a shortage of drivers now, we believe that this technology will be applied first to address the shortage. we think there are going to be plenty of opportunities for human drivers for the foreseeable future. so how do truckers feel about theirjobs being threatened by self driving rigs? you ask any truck driver,

they don't want to be behind a nine to 5 desk, somebody telling them what to do, pick up that, do that, do this. if you are in a truck, eight hours a day, you are driving, you're by yourself. listen to your music. you've got peace. there was an accident here in town of a car, self driving car, so how catastrophic it would be with a truck. if something went wrong. what i going to do then? stand in line for food? that's what it's coming to. and you know it is. i'm kind of sceptical. to see how the safety rating is going to be. but i know that they have been testing it and so far, so good. it's not going to happen completely, and get people out ofjobs. no. there's always going to be human beings driving the trucks. have you ever known a machine... - that can go down the highway

or function right? _ they don't always work, it's true. now it doesn't work. look at the accidents that have happened already. l need i say more? but let's not get ahead of ourselves. these drivers almost certainly have a while yet before theirjobs disappear. while the advancements that we have seen in the last few years are more than impressive, getting your computer to fully understand the real world and drive safely through it, will be a monumental achievement. they are not saying that it's done, because it's not. this is not a solved problem. this is a hard problem. it is many years before you can buy a car that has no steering wheel, and you can say i will have a car with no windscreen and it has the same functionality as your car does now. to start with, they will have

subhuman capacity and superhuman capacity in other things. subhuman in their ability to reason about all the extraordinary things that can happen on a road that's got nothing to do with driving. superhuman in their ability to concentrate and never ever ever get distracted. to see in ways that humans don't see with radar and laser, to sense distance. extraordinary things. and above all, the ability for these vehicles to share and acquire competencies, not because of their own experience but because of the experience of other vehicles everywhere else in the world. that's an extraordinary thing and that is the compelling reason why these vehicles are coming. they will be better than us because there's nothing in our evolutionary history that makes us good at controlling a tonne and a half of metal at 70 miles an hour. here in arizona, i have seen the benefits of and the resistance to the idea of the machines taking over another part of our lives. so i think the question is not if, or when, this will happen. but will we let it?

hello there. the first half of the weekend has been cold. the second half of the weekend starts with frost. and sunday promises to be another chilly day for the time of year — there'll be some sunshine and wintry showers around, as well. now this was the picture on saturday at buxton in derbyshire. i know it's high up, but we had a covering of snow for a while. towards more southeastern parts of england, it was cloudy skies with some rain and drizzle — that damper weather has been moving away, it's been on that weather system there that's heading into continental europe, so the cloud is breaking towards the southeast. we've got high pressure to the west of the uk,

a northerly breeze bringing in the cold. so we start sunday with a widespread frost, it'll be a colder start for the southeast of england and east anglia as the cloud breaks, lowest temperatures likely to be in northern scotland at minus seven celsius. and there could be some icy patches around too. still a few showers first thing, although many places will be starting dry and sunny, cloud will tend to increase, we will see a few more showers make out in the morning, and they'll turn more widespread in the afternoon — some of them heavy with hail, sleet and snow mixed in there, as well. it'll be another cold day, temperatures typically 6—8 celsius, maybe a touch colder than that across northern scotland, a touch milder than that across southern parts of england. but the damp weather coming into northern ireland by the evening on that weather front there, that'll slide its way down into wales, the southern half of the uk. but a frosty start on monday for many, particularly cold for northern england and scotland where we have the clearer skies. for the most part, monday here should be dry and sunny, just a few showers near some eastern coasts. should brighten up through the day in northern ireland,

but stays quite cloudy through wales, the midlands towards southern england, some patchy rain — and early in the morning, it could be a touch wintry in the midlands as we engage some of that colder airfirst thing. temperatures will be a notch up on monday, but still cold for the time of year, around 8—10 celsius. now looking further ahead, we've got high pressure turning to dominate the weather through the week ahead, and that means the winds will be light, there'll be some morning mist and fog patches. you'd expect it to be dry underneath an area of high pressure — may not completely be the story, though. there's a risk of a few showers around, especially during the first half of the week. many places will be dry with sunshine, a little less cold by day and night.

this is bbc news: i'm lewis vaughanjones with the latest headlines for viewers in the uk and around the world. prince charles pays tribute to his father the duke of edinburgh, as details of the royalfuneral are announced. the prince of wales said the duke had given devoted service to the queen, his country and the commonwealth. my dear papa was a very special person who i think, above all else, would have been amazed by the reaction and the touching things that have been said about him. in other news, as france steps up its vaccination programme, the jab will be offered to everyone over 55. india's record number of daily infections, a reluctance to wear masks and over—crowding are blamed.
