Picture yourself in the not-too-distant future driving your new car
along a rural interstate highway on a business trip. The cruise control is
maintaining the speed at a steady 100 km/hr (62 mph) and there is relatively
little traffic. As you approach a slower car, the speed-control system slows
your car to match the speed of the slower car and maintain a safe distance of
about 53 m (165 ft) behind the slowe/r car. When oncoming traffic clears,
you enter the passing lane and your car automatically increases speed as you
pass the slower car....
