Evidence: The Google car for example, has sensors on the left rear wheel, a rotating sensor on the roof, a camera on the rearvier mirror, four automotive radar sensors, a GPS reciever, and an inertial motion sensor. The car runs off of all of these sensors, and needs every single one of them to run properly. But what happens if one of these sensors reade untrue values because they have malfunctioned or got covered up by something. Technology can only go so far into our lives before we are putting human life at risk. All it takes is one failure, one moment where a sensor isn't working correctly , and a persons life could be over. The sensors also cost money. This would make many of these cars almost unbuyable to the general public because of the cost of parts and matenience.
