If cars driving themselves will asymptotically approach say 90%, 95% or 99% or situations it can handle, then the car that also handles the last few situations will be very attractive. That's the car that can drive me home from the bar, or that a blind person can own. The 90-99% cars are still for able bodied people with licenses.

At some price point, it will always be a lot cheaper to add humans than it is to make the cars "self driving". And the last % I'm almost certain will never be cheap enough for autonomy.
