The system acts slowly and and is only active if the driver has engaged it (like cruise control). You'll be driving at 120kph and you'll notice the car has slowed to 118kph because it thinks the speed limit is 100kph. You push the accelerator and update the speed limit. Done. I honestly can't see this causing an accident. The thing isn't performing an emergency stop or anything.
