It won't be consumers who drive the adoption of robot cars, it will be the logistics companies. This will all start with factory-to-doorstep supply chain integration.

First, Amazon and Wal-Mart and Fed-Ex will have giant fleets - then consumers and mid-sized businesses will follow. Small local governments and developed Asian nations like South Korea and Japan will also drive adoption.

Having a fully-automated supply chain will break the competition who doesn't have the capital to get there fast enough. The big companies already automate the factories, and once delivery is automated, the circle is complete.
