text: Driverless cars also help with the short attention spen of a human. People can be alert and aware on the road, but not all of the time. Humans can get tired, bored, and let their mind wander. With driverless cars, people would be allowed to let their mind drift, as long as they can be alerted when they need to take over the car. These cars would be able to do that with flashing lights, vibrating seats, annoucements, and other alerts. The car would do what it is able to, and when it needs a driver to take over, it simply lets the person know. The manufacturers are also considering using cameras that watch the driver to make sure they are paying attention.
