text: In order for the car to prevent accidents, it must have sensors to tell the driver when they need to take over. These sensor could stop working at any given time. For example, we all like to use the internet on our phones and computers. When there is a terrific storm our conncection may not work. What happens if a wire breaks on an important sensor? Then an accident comes up and we do not get an alert. That can cause a very serious wreak.
