Embedded systems can also make driver-less vehicle control a reality. Major automobile manufacturers are already engaged in work on these concepts. One such technology is Adaptive Cruise Control (ACC) from Ford.

ACC allows cars to keep safe distances from other vehicles on busy highways. The driver can set the speed of his car and the distance between his car and others. When traffic slows down, ACC alters vehicle speed using moderate braking. This ensures that a constant distance is maintained between cars. As soon as traffic becomes less, ACC moves up to the desired cruise speed that has been set by the driver. The driver can override the system anytime he wants to by braking.

Each car with ACC has a microwave radar unit or laser transceiver fixed in front of it to determine the distance and relative speed of any vehicle in its path. The ACC computer (what else but an embedded system or a grouped system of embedded systems) constantly controls the throttle and brakes of the car. This helps to make sure that the set cruise speed or adapted speed of traffic at that time is not exceeded.

Another revolution is the way Internet services will be integrated into the car. So when you drive past your mechanic's, you will be reminded that your engine oil needs a refill, and when you cross the city limits, the toll will automatically get deducted from your bank account. And while passing the shopping mall, your PDA, which is connected to the Net via the car, will inform you about a new sale. In fact, the automatic toll deduction concept is already in effect in several countries around the globe.
