The personal autonomous car is just the first, simplest version of the autonomous vehicles.<p>It won&#x27;t be long before much smaller, short-distance, rentable systems come out -- self-balancing cycles that convert to cycle-trains, and so forth.<p>As autonomous vehicles makes roads much safer, two-wheel systems that are currently too dangerous will become much safer, and much more desirable.<p>As people are less inclined to own their own vehicle, and as delivery systems are more common, there will be less incentive to own a large car. People will rent two-wheel autonomous bikes instead of four-wheel autonomous cars, if its going to cost half as much.<p>The profit motive alone will solve these issues.
