Thanks to the California Autonomous Vehicle Testing Program, the state has become the most-popular place in the world to test out self-driving vehicles on public roads, and Ford is the latest company to secure a permit to do so. BMW, Google, Honda, Mercedes, Nissan, Tesla, and Volkswagen have already received similar permits, and Google has been testing out its self-driving vehicles on California roads for a while. Ford will begin its own testing sometime next year, using a small fleet of autonomous Fusion Hybrid sedans that were developed at its research center in Palo Alto.
