text: In 2013, BMW announced the devolopment of "Traffic Jam Assistant." the car can handle driving functions at speeds up tp 25 mph, but special touch sensors make sure the driver keeps hold of the wheel. They can steer, accelerate, and brake themselves, but all are designed to notify the driver when the road ahead requires human skills ,such as navigating through work zones and around accidents. This means the human driver must remain alert and be ready to take over when the situations requires. This necessitates the car being ready to quickly get the drivers attention whenever a problem occurs.
