1)audi pre-sense activated while vehicle was stationary, in drive, with driver's foot on the brake. this occurred while waiting in the left turn lane of a traffic light. the seat belt pre-tightened suddenly, and forcefully. while the vehicle is stopped at a light the occupants could be expected to be leaning over, looking in the glove box etc., and the pre-tightening of the seat belt could cause an injury. this is also startling, since it seems indicative of a collision, and could cause the driver to remove their foot from the brake losing control of the vehicle. the pre-sense system is supposed to only be active above 20mph. its activation when the vehicle is stopped implies a serious safety defect. could this defect cause other safety related systems to activate incorrectly like the air bags?
