This driver-less, auto-pilot car idea will create new problems. Human nature being what it is, people will find ways to abuse the system. Imagine trying to get somewhere in a city and pedestrians keep walking out in front of you, knowing the vehicle will stop. The frustrated driver will disable the feature so they can continue their mad rush to get from point A to point B. Then it possibly will be viewed as 'only old people and morons use the auto-pilot, it stops too often and doesn't go fast enough'.
Just thinking on screen, is all.
