text: My other reason for being for driverless cars is they would allow the "driver" of the car to be doing something other than driving. BMW has been working on this feature of the driverless cars. They use a headsup displays in the car the show a form of entertainment and information systems to entertain the diver. And sence the driverless cars still need some driver assistance the display instantly turns off when the driver is need. This feature is not in a normal car. If the driver was need and they were texting the phone wouldn't turn off, there for making the driverless cars safer.
