The Institute of Electrical and Electronics Engineers, a technology professionals association, predicts that autonomous vehicles will likely make up 75 percent of cars on the road by 2040. Additionally, IEEE says road infrastructure like lights and signs may disappear, along with the need for driver's permits.
The organization has already put its theory to the test with the computer engineering department at Italy's University of Parma, piloting two self-driving vehicles on a trip from Parma to Shanghai.
Cadillac, Audi and BMW have all created automated cars, with Cadillac predicting that it will be rolling out driverless automobiles by the end of the decade. Google has also been testing a fleet of cars that drive themselves, while lobbying Washington, D.C., to get behind the technology.
The Mercury News reports that California is already on its way to automated vehicles on its roads. The California Legislature has sent a bill to Gov. Jerry Brown that would allow for driverless cars on the roads by later this decade—a bill that if signed might spur even more innovation by major technology companies.
