That could be more distracting than the distraction it's trying to detect.
Our car warns you when it thinks you're about to crash into the car in front of you, and it does so with a very loud and annoying noise. I hadn't noticed it for years until it suddenly went off several times in a couple of days, so maybe there are circumstances where it gets overly sensitive.
Of the 3 times it warned that I can clearly remember, 1 was correct: I was indeed getting close to the car in front of me (I was aware of it and was already about to start braking when the alarm went off. The other two were I think the shadow of a viaduct I went under, and probably a parked car next to the road.
It also seems to detect max speed based on signs next to the road. Fortunately it doesn't do anything annoying with that information, because it's frequently wrong.
