text: Second, with Google Cars it would be easier for a wreck if the car malfuntioned. It would be easier for the car to malfuntion becuase, for example, say you were in a Google Car and you got a warning that your break fluid was low, you wouldn't know becuase you weren't paying attention to your car. Also, they have made a sensor that goes on the roof of your car so that the car can see all around your car. If that sensor malfuntions, the car wouldn't be able to see where it was going and you could wreck. For example, "The most important bit of technolofy in this system is the spinning sensor on the roof. Dubbed LIDAR, it uses laser beams to form a constantly updating 3-D model of the car's surroundings."
