One good thing about the car is that they have a lot of sensors and cameras on them. They also thought of a good way to make sure that the human driver in the car is prepared to take over. " The Google car simply announces when the driver should be prepared to take over."

People were also thinking about a camera that watches the human driver watching the road so that they are remaining focused on the road at alll times.
