Out for a motorway drive today, and left the motorway via an exit ramp at around 60mph, and some clown does the same but races up my ar$e and left his braking too late.... all of a sudden I hear a very loud beeping and the guy backs off frantically....

I don't have the traffic sensors (although have allround parking sensors), so does anyone know if this is standard? It seems it warns you for impact... and the way the guy backed off I wonder if my brake lights were flashing at him (I was NOT braking at the time).

Would be great to know if this was an intended safety feature, if so, it worked !

Not sure but I wish that worked for us and our 535i...a drunken geriatric accelerated into our rear bumper with a POS Honda Pilot in gridlocked freeway traffic. No fun.

No fun at all... hope the damage was not too bad! Did you happen to hear any beeping?

Collision Warning only works to avoid collisions in front of the F10.

[AP]

and even then, it might be too late. Its only designed to limit the impact rather than prevent a collission in the first place. I've recently posted up a thread about BMW implemenation

It doesn't appear to be the best out there, perhaps the LCI will improve matters?

Thanks folks (interesting read). Was aware of front collision, but thought this was non-standard unless you order it.

Anyway, I think the interesting/important thing is that my car beeped like crazy when the person raced up my rear-end... it happened... so am happy for that feature whatever it is !

You probably heard the "Anti Collision Warning" from the car behind you.

You may have heard the rear parking sensors going off immediately before impact.

Based upon my experience it works quite well for collision avoidance when set to give the earliest warning. It will not prevent a collision per se by applying brakes, however the early warning system gives one an early warning that is most helpful.

If it was a Volvo in your rear, it might be possible, the collision warning is really loud in the Volvo, and yes it does actually work as well, warning, full break, and a "HUD" red strip of warning lights

About $9k worth of rear bumper/trunk/muffler damage and no beeping. On the plus side, I'm getting a pretty cool Magnaflow cat back exhaust out of it though!

It was definitely my car.... it came from the dash/above my head (map-light cluster) I recall or could even have been from speakers... nothing showed on screen

So what you're saying is, the guy behind you, travelling at speed in another car, backed off frantically after he heard, from your car, a beep from above your head?

It is more likely that the beep was either unrelated or for some reason your rear PDC sounded. His braking is nothing to do with your car, its to do with the fact he slammed on the brakes too late.

How would a loud beep help in any event? A momentary bleep to allow you to kiss your ass goodbye? lol

Actually no... the beeping was in my car and only I would be able to hear it...
I suspect he backed off quickly either because he suddenly realised how fast he had gone behind me when he saw my bumper in his face... OR there may have been some automatic brake lights flashing on my car that triggered his sudden reaction...

The momentary beep could actually brace you for whiplash, or attempt avoidance tactics to get out his way

Divine Intervention perhaps?

All's well that ends well!
