When Do Robocars Become Cheaper Than Standard Cars?

Hallie Siegel writes: With all the extra sensors and technology that have to go into autonomous cars, you might expect them to cost more. After all, autonomous features like park assist and auto lane changing are added-value components that you pay extra for on current vehicles. But autonomous car expert Brad Templeton thinks it could be that the overall cost of autonomous vehicles per mile driven will lower than traditional cars. Not only because features of traditional cars, like dashboards and steering columns, will not be necessary in robocars, but also because autonomous cars are more likely to be shared and constantly in use, rather than sitting in your driveway 90% of the time.
