One reasonable scenario for rapid  deployment of self-driving cars - is shared vehicles, driving a few people at a time over a shared but optimal route.<p>It&#x27;s possible that such vehicles will have 5x-10x total occupancy per day of regular vehicles(which sit idle at most times). And it could imagine how the right financial incentives would shift a large share of the manufacturing capacity towards such cars.  And considering the car replacement rate at probably something like 20 years - maybe 10 years is a possibility of starting to have that conversation.
