text: The driverless cars will be a safer car. These cars have been driven more than half a million miles without a crash. The makers of these cars believe that more states will follow as soon as the cars are proved more reliably safe. The reason for this is the senors to alert the driver. The senors tell the driver what is all around them. Another reason these are good cars, is that they use less fuel than the average car, and it will have more flexibility than a bus.
