Calif. Green-Lights Self-Driving Cars, But Legal Kinks Linger

Google co-founder Sergey Brin, who was also at the ceremony, jokingly said "self-driving cars don't run red lights."

That may be true, but Bryant Walker Smith, who teaches a class at Stanford Law School this fall on the law supporting self-driving cars, says eventually one of these vehicles will get into an accident. When it does, he says, it's not clear who will pay.
 
"The question becomes: If you put a 15-year-old in the vehicle and press the go button, are you — the person sitting at home — the driver, or is it the person in the car?" Walker Smith says.
