Well, it does not talk about the main problem that sef-driving cars have today: One cars works ok, as it uses an active super expensive light(Lidar) and radar sensors. Put two cars together using the same LIDAR light or the same frequencies and you have a terrible problem. Also using Lasers will be dangerous when people look at the thing and the thing is working near you as the power of the light could do bad things to your eyes and you don't see it.
