text: There are companies now that have cars that drive, for exmple Google and BMW. Google has had drvieable cars since 2009 and they have driven more than half a million miles without a crash, but there is still a person in there that has to help out. Although the cars do drive them selves, they can not go through work zones or go around crashes, so the human has to come into play. BMW has a car that they call "Traffic Jam Assistant", this car can handle driving speeds up to 25 mph, but drivers still need to keep their hands on the wheel and when the car does not know what to do then vibrations go through the seat to notify the driver.
