Active Cruise Control on the BMW 3 Series Convertible.

Freeway driving can be so relaxing: the BMW 3 Series Convertible with Active Cruise Control (ACC) maintains your pre-set speed on the open road. When a vehicle enters your sensor field, ACC reduces your speed if necessary to maintain the distance that you have defined. When the lane is free again, ACC returns the vehicle to the desired speed. Touch on the brake or accelerator pedal and ACC deactivates immediately.
