text: Safety is not the only issue when it comes to driverless cars. Owning a driverless car would be extremely expensive. As I said earlier, mechanical failuers happen all the time in cars today. The cost to fix your car when something happens is already expenxive. If you were to own a driverless car and something happened to fail, the cost would most likely be exorbitant. Driverless cars have so many features and sensors. In section four, it says that there are sensors on the left rear wheel, a rotating sensor on the roof, a video camera near the rearview mirror, four automative radar sensors, a GPS receiver, and an inertial motion sensor. If one of these sensors were to go bad or to break, it would be costly to fix them.
