Teslas vision based system makes a prediction of what the environment around it is, how far away things are. A LIDAR based system knows with certainty how far way things are. LIDAR may be expensive now, thats not to say it won't get cheeper, with fewer parts. But the main issue is a social one, I don't think the public will except any fatalities as a result of a vision based system making a mistake. Even if the deal rate from accetends is lower than with a human driver. A self driving car can't be 50% better, or even 200% better it needs to be thousands of times better than a human driver for it to succeed. I think the certainty of a LIDAR baed system is the only way to do that. An AI based vision system is Tesla saying that can make a "brain" better than a human at understanding vision. LIDAR is saying, humans can't measure how far away things are, we can do better than humans by doing something they can't.
