text: In 2013, BMW had announced that they developed the " Traffic Jam Assistant." They said that the cars are not developed enough to completely drive themsleves. The cars can steer, accelerate and brake by their self but if the can requires any human skills the car will notify the driver. GM made the driver's seat to vibrate when the car is near danger. Google's car will announce when the driver will be taking over. With all these heads up, there shouldn't be any accidents.
