Great, Just what we need more falses from other locations. I know I get a 'pop' warning when I'm following tri-axle dump trucks close and they have their foot on the brake. Now we get to deal with rigs.
Forward collision warning/adaptive cruise control system. These systems use forward-mounted radar to detect vehicles or other objects in the road ahead. Adaptive cruise control uses radar to maintain a safe following distance behind vehicles. Some systems issue collision warnings, while others can take actions to slow down the vehicle to avoid a crash.
Lane change/merge warning system. These systems use side-mounted, short-range radar or ultrasonic waves to "see" vehicles in the driver's blind spot and produce an alert if the driver attempts to merge into an occupied lane.
