What if the car was smart enough to identify situations where it was unable to auto-navigate safely? It could pull-over and ask the human to take-over for awhile. I would rather see a mostly capable self-driving car come to market sooner than wait around for near perfection.
On this note, it seems that the trucking industry could adopt a self-driving truck even if it was only good enough to travel along long stretches of highway. The first/last miles would be manually driven just like today. Could the trucking companies use remote navigation (much like military drones) to handle first/last mile and perhaps problem spots along the way?
What's the minimum viable product?
