Tesla's vision is fine but re autonomous driving
How does one deal with the human element, such as 1. Wanting to pull over suddenly to look at a nice view or take a leak? "Car! Quick, pull into that lay-by!" How will car know which lay-by? A human passenger would gesture to the driver, pointing. Can internal camera see what the occupants are doing?
2. And there hasn't been any discussion as to what Tesla's AI will do when faced with two unavoidable collisions:
a) Elderly couple crossing the road or b) Younger mother with child?. If course, this situation is rare even for humans, but owner of vehicle should be able to specify. This will also move the burden of responsibility away from Tesla (or other manufacturer) to the owner for insurance etc purposes.
