text: Safety of the driver and the passengers also plays an important key role in driveless cars. When the technology increases I think the safety of the driveless cars will increase to because Google said they had a project car that went over five hundred thousand miles without a crash. In a driveless car today though the driver must stay alert at all times, because any kind of a situation can come upon such as navigating through work zones or around accidents. Google and GM have developed warning signs to tell the driver when the driver should be ready to take over.
