text: Last, but not least, the car can handle driving functions at speeds up to 25 mph, but special touch sensors make sure the driver keeps hold of the wheel. None of the "driverless cars" actually developed as diverless. They can steer, accelerate, and brake themselves, but all the cars are in fact designed to notify the driver when the road ahead requires human skills, such as navigating through work zones and around accidents. So therefore, the human driver has to remain alert and be ready to take over the car when the situation requires.
