except driverless cars have been driving around in California for a couple of years thanks to Google (and the fact that it's legal). Soon the term "driverless" will be like "horseless". Why would you keep your eyes on the road when a machine will do it for you, and with more awareness of its surroundings at 360 degrees, and the ability to judge the position and trajectory/velocity of any object to within a couple of m/s instantly, or react to anything in milliseconds?

Don't kid yourself: humans aren't some kind of perfect driver. A bit of sleepiness, a text message, a tiny distraction in the car, and their responsiveness plummets.
