text: In the passage, the cars that are being tested are not completely driverless yet. The passage said that the car can only do so much without a human, if there are accidents and work zones on the road then it needs a human to control it. According to the passage, General Motors has been working on things to get the driver's attention when the car needs a human, they have been developing driver's seats that will vibrate if in danger. Some of the other options that companies have considered is to have flashing light on the windshield and some other heads-up displats. Another option is the idea where they have cameras watching the driver so that they know whether or not the driver is focused on the road.
