brian womack joining us on the phone. he just took the test drive in the google driverless car. testingy they have been the cars now for years. i have driven and one of them myself three years ago. what is it like today? >> very smooth. them off toto show reporters yesterday because they have really been tackling the issue of getting them to work on surface streets. not just freeways but surface streets. navigating the yellow, red lights all those things. in there it did a pretty good job. i was impressed. more gentle than i might have expected. in the car three years ago it was a little bumpy. a littleing was abrupt. would you say this is closer to being ready for prime time? >> yes. good and bad. one stop where it was such a nice soft stop. very well done. the drivers ed teacher would have been proud of you. there was another time where it gave a lot of following distance to the car in front of us because of other issues going on around a railroad track which i do not think most of us would get that much space. there is a lot of progress here, but it is not perfectly analogous
