California allows cars without human drivers
 

No-one is better than some of our drivers, so lets use no-one

California has become the first US state to allow the testing of automatic cars without a driver behind the wheel.

Most US states require a driver to be behind the wheel of driverless cars in case they need to take over in case of emergency. Some US states require a man on a horse with a red flag to go in front of the car during testing. Of course having a bloke behind the wheel makes no real odds. If there is an emergency they have to put down their book, put the cover back on their coffee, press pause on their video and then react to the crisis the robot could not handle.
