Liability Issues Create Potholes on the Road to Driverless Cars

Bryant Walker Smith, a lecturer at Stanford Law School who has studied driverless vehicles, said the new laws leave many issues unaddressed. In part, that is because fully driverless vehicles are many years away.

"We don't actually have a fully self-guided car," Mr. Smith said. "We don't know how various aspects of that will be introduced. We don't know how they will ultimately perform or what 'safe' is.…It would be much easier to analyze the legal uncertainty if we had an actual product out there."
