I have it on my car. I think your concern isn’t an issue in reality. I have never seen it kick in while being close to someone’s bumper.
It has only kicked in in three situations, all of which have been warranted.
* I was turning onto a main road. Foolishly, I assumed the car turning in front of me went. I started making my turn. It alerted me and avoided a minor, but costly rear end.
* in dense traffic where people cut in and out. In the time it takes to verify a lane change, someone has cut you off or traffic has slowed. It doesn’t not apply heavy braking, but issues an audible alarm and pretensions the brakes.
* once in a situation where I misjudged the braking speed of the car in front of me. The vehicle was a bit smaller than I though, so it appeared further away at speed.
In the latter two cases, the actual emergency braking did not engage. Only the pre warning and tensioning. In both situations, I would have likely avoided an accident without the system, but had to apply by brakes even harder.
My understanding is emergency braking doesn’t necessarily avoid a collision, but it can bleed of speed in the final few feet before an impact. A collision ending 2 feet into your bumper is far safer than one ending 10ft into your car.
