Who’s Responsible when a Driverless Car Crashes? Tesla’s Got an Idea - WSJ

Shorter answer: not Tesla

"Tesla Motors Inc. is looking at the good old-fashioned turn signal as a potential solution to a liability debate associated with driverless vehicle technology.

The Palo Alto, Calif., electric-car maker soon will begin activating semiautonomous features, including the capability to pass other cars without driver intervention, in its Model S sedans. A driver can trigger the passing function by hitting the turn signal, according to people familiar with the technology. That action not only tells the car it can pass, but also means the driver has given thought to whether the maneuver is safe."
