text: Driveless cars allow people to be notified of their surrounding so that they will not run into things. For example, " GM has developed driver's seats that vibrate when the vehicle is in danger of backing into an object." This feauture allows the driver to know when it should stop reversing by adding vibrations to your seat so that they will not hit anything. When the driver feels the vibration it will know that there is an object neerby and it is necessary for them to stop. This will cause less accidents and make it safer for people to drive. The " blind spot" while driving will not longer be a problem while driving because you will now have a sensor that tells you when you are to close to an object making it safer to drive.
