One thing I'm looking forward to with self-driving cars is to be able to step into a street anywhere and have all the traffic stop automatically. Every inch of street now becomes a crosswalk. Even highways. (This is an ironic statement)
In all seriousness though, what would happen in this case? Do self-driving cars have emergency stop procedures? And how safe are they? This is still a serious concern about self-driving cars for me. Especially since digital image recognition still isn't that great. What if the car sees a tumbleweed that it mistakes for a boulder and puts it into emergency stop mode?
I believe digital image recognition is better than human, and a lot faster to boot (hah!).
