content: It was 8:30 according to the guy in the video. As for negotiating traffic, the car will just stay in lane. This isn't self driving in the strict sense as it won't follow the navigation system and it will only change lanes if you indicate and then it verifies the surroundings and makes the change. Slow moving busy traffic is exactly where this shines though as it will maintain distance and speed to the car in front and stick within the marked lines. My only concern is if the car in front crashes and while I expect the tesla would stop in time, the meat controlled car behind probably wouldn't.
