The list of automakers that can test their self-driving cars in California is getting less and less exclusive by the minute. Its latest addition? Subaru. The Japanese company has secured an Autonomous Vehicle Testing Permit from the state's DMV on February 9th, bringing the total number to 22. Some Subaru models already have assisted driving features thanks to their camera-based Eyesight system, such as adaptive cruise control, sway warning and pre-collision braking.
