Autonomous cars may dramatically expand the set of people that can drive cars, which will accordingly increase the amount of cars on the road. Right now the set of potential drivers are limited to 16 to around 80 (though many seniors may be forced to stop earlier). When skill and attention and licensing are no longer requirements for driving, then children and seniors that would have been forced to bicycle, walk or take transit will be able to call an autonomous car.
