The State of California Department of Motor Vehicles recently approved Subaru to be on its list of cars approved under its Testing Autonomous Vehicles program. This brings its list of companies that have permits to test next-generation self-driving cars to 22. Many of the firms on the list are famous, global vehicle manufacturers. Nearly as many are not household names, or brands that anyone outside the industry has heard of. The list shows that the self-driving car industry is broad and some of the most important future players may edge out behemoths like Volkswagen, BMW, Ford Motor Co. (NYSE: F), Tesla Inc. (NASDAQ: TSLA) and Alphabet Inc.’s (NASDAQ: GOOGL) Google.
