California is fine with car makers test-driving autonomous vehicles on its roadways, but the DMV now has some rules on exactly how. Under new regulations, drivers (or riders as the case may be) will need to be official testers on a manufacturer's payroll and go through a special training program to get a yearlong permit. They'll also have to remain attentive behind the wheel -- so no napping on the way to work yet -- and notify the DMV if they're in an accident or have to override the car's manual controls for any reason. When it comes to cars, it's not a free-for-all. Manufacturers will need to apply for a permit for each individual vehicle, and cars are required to have at least five million dollars worth of liability insurance.
