Even 15 mph, there is still a point of no return were the car can not avoid a person. Example in downtown Dayton. A big delivery truck parks illegally near a cross walk. A person walks out from behind the truck. He is hidden from the car, and gets hit. Now if there was a pedestrian signal and the guy can see, "Ok it is safe to walk", that takes out this scenario.
Also knowing the cars are programmed to avoid conflict, does that give to much of a free will for humans to just run out into the street?
I rather have some sort of redundancy in the form of pedestrian signals. All it takes is one F'up and the City or Town + google is sued for millions of dollars because the defendant will ask the question, "Why did you take away our traffic signals?"
That will only happen with a human driver. The plan is for sensors to be placed all around the vehicles are designed to prevent this kind of accidental injury. Even our "dumb" model vacuums have sensors all around to prevent damage to furniture and other things.
The only real way to "fool" the robot is to jump out in front of it while it is cruising along at a substantial speed. The pedestrian would need to be in a location he/she is not designated to walk. The main thing is that it needs to be programmed with the human occupant's safety first. It needs to weigh the two options. The person jumping out in front of the vehicle would be at fault, while the occupants of the vehicle are innocent of any wrongdoing. This type of behavior and similar ones would be hard programmed into the system.
I agree that a pedestrian would still have the right of way, and that crosswalks would be programmed as "slow zones". The vehicle would slow down at every crosswalk, as a human driver should.
Parking will probably still be an issue, but the vehicle may not allow itself to park in a non-designated spot. More than likely it could be programmed to drop off occupants and/or deliveries, then continue to drive around until it finds a space or if the occupant signals it for a pick up.
