I wasn’t long in the backseat of Google’s self-driving Toyota Prius, cruising smoothly down California Highway 85, before a sober, gray-flannel question pierced my giddy techno-utopian buzz: Is this legal?

On principle, it would seem downright churlish to penalize Google’s upstanding Prius — which kept letter-perfect lane position, following distance and speed-limit compliance — while all around us human drivers committed a panoply of illegal acts: talking on their phones, speeding, changing lanes without signaling, tailgating, you name it.

But what does the law say about autonomous vehicles?

Apple has confirmed maybe the worst kept secret in Silicon Valley: it’s been working on a cloud service, and will announce it at the June 6 Worldwide Developers Conference.
