I was driving my QF into central London this morning when the car in front of me slammed his brakes on as a pedestrian stepped out into the road. I started braking but the car obviously thought I wasn’t going to stop in time and activated Forward Collision Avoidance. It enhanced the level of braking and brought the car very quickly to a stop (luckily no-one was behind me). I was really impressed with the technology and can definitely see the benefits. I have been pleasantly surprised by the safety/assistance technology in the QF that comes as standard.

Interesting. Do you think you would have stopped if it hadn't "helped"? My wife's LR did it to me a while ago, in my view completely unnecessarily as we were approaching a roundabout.

I think I would have done, but the car definitely helped stop much sooner than I might have.

The trouble with that is that you ended up braking much harder than needed and thereby increased your chances of being hit from behind. Obviously it could have saved you crashing if you had misjudged it but it could also have caused a crash if the car over-did it.

But the bonus in that scenario is that if you're hit from behind it's their fault, if you hit the car in front it's your fault!

Maybe, but depends how far back he ended up from the car he was avoiding. If only a foot or two then it was the right thing to do, but perhaps over-sensitive if it ended up with many car lengths to spare. Never an easy call to make in those critical situations, but probably a good start not to plough into the back of the car that stopped suddenly.

My car has both AEB and an audible early warning collision detection signal. You can adjust the sensitivity of the latter, so if you set it to the most sensitive setting you get a very clear audible warning if something ahead decelerates suddenly. Only if you ignore the warning and continue on collision course does the AEB actually kick in as you get closer. So far I have only had a couple of false warnings when approaching stationary cars in narrow roads before pulling out to pass. In neither case did I get close enough to the parked car for the AEB to intervene, which I think is a good compromise.

That’s exactly my experience in the QF. The system is set to the least sensitive setting, so if it intervenes, it genuinely thinks you need help!
