text: The human does not have complete control on stopping the vehacle. GM has a special development , when ever the vehicle is in danger or is backing up into a object the seat vibrates. and when the vehicle cant manage somthing the human can it announces the human should take over and it sends other ways and signals the driver another way if not seen that way. there is also another way to keep the driver focused on the road and to make sure there are cameras watching the driver to make sure the drivers remain focuesed on the road, while the driver watches the road, the car watches the driver.
