in pt barnum is about celebrating because he is very good so he would say something and then talk andry to sell the story and when people would flock to his museum a few days later turning to another newspaper so then they write an article debating the other one. [laughter] and it was a media fight people thought really? it wasn't real? so they went back to take another look and paid again. [laughter] so this is the assumption that i teach in my class that it is true that of perception to realize that on game leading to democracy of how you imagine the other way. so with that game with a sense of politician to win your confidence and trust that that is very much alive because pt barnum started the competition like the beauty contest. [laughter] so just like the earlier freak show. >> and was thinking of response of what you said but all three of you are basing your work on sources so what about the role of media as a source? is it accurate is it now wasn't then? is there a continuum of how much to trust the media and which do you trust? >> i have an extensive bibliography at the end o

there is a lot of pt barnumism, a lot of speculation., we always test with two engineers, one at the wheel and one in the backseat with the data. you need to work with consumer understanding and with regulators, but it is not a sprint. getting it right is what winning is to us. we think we can and will get it right. >> i think many people share that view as well. i wonder to what extent many of these developments have had free reign on public roads to develop this technology and whether the legislators will clamp down on that? >> that is what you are seeing in arizona right off the bat. the best thing with regulation is to have absolute transparency. they need to share the data. they need to see the data. the biggest word we keep using is trust. do the regulators trust the technology? does the consumer trust the technology? and of course, can we deliver? that is the ecosystem you are seeing broken up right now. the other thing we need is we believe strongly that you need a federal standard. that will get away from each state coming up wi
