Waymo, a driverless car company owned by Google parent company, Alphabet, has a fleet of driverless vehicles that have logged the company millions of kilometers driven on real city streets, but the bulk of its deep learning comes from driving on virtual roads. Developers for the company are training more than 25,000 autonomous vehicles over 12 million kilometers (8 million miles) of simulated roads driven every day.

The simulations involve highly complex situations including multiple lane intersections and irregular vehicle traffic. Not only are these virtual driving schools informing deep learning models for each specific vehicle, they help to create data that allows driverless cars to network together. This adds an extra layer of safety for everyone including pedestrians and human-driven cars. More…
