text: In the 1980's automakers used speed sensors on the wheels for the creation of antilock brakes. Although sensors are not new creations the sensors on "driveless cars" tell the car when to slow down, speed up, or even stop. Companies plan on improving these sensors to make driving "safer" and so that the cars can actually become "driveless". As none of the "driveless" cars produced so far are not actually "driveless" but still require "driver assistance". Meaning the driver can't just sit back and relax they have to stay alert and be ready to take over if something should happen. GM has developed seat "notifications" that tell the driver when they are backing into an object. These seats vibrate to alert the driver of the objects behind them.
