text: First, if the car was to break down and the sensors were messsed up it would be very expanisive to fix. According to the article, "Totyota Prius uses position estimating sensors on the left rear wheel, a rotating sensor on the roof, a video camera mounted near the rearview mirror, four automotive radar sensors, a GPS reciever and an interial motion sensor'. If you were to get into a bad car crash and wrecked the car and wanted to get it fixed it will be super expansive. Mainly because all though sensors are high tech and advanced. So basically your fixing the car and paying for all the technology it needs which is going to be alot of money.
