The perpetrator was me.

In a hire car travelling in lane 3 of the M6 overtaking slower traffic with my adaptive cruise control on.


A faster caught up with me from behind.

I saw a fair sized gap in lane 2 I could slip into, allow the faster car to pass then slip back out behind him, all without needing to adjust speed. As such the adaptive CC remained engaged.

When I slipped into this gap my adaptive cruise control took the view I was crashing into the car in front and stood me on my nose severely brakechecking the poor bugger behind.
Fortunately there were no collisions.

As far as the car I pulled in front of to brake suddenly and randomly is concerned I must be psychotic. If he had a dashcam fitted a well deserved visit from the police wouldn't have surprised me.

If I'd told them what happened how would they react?

The ACC is set to the wrong distance parameters for the speed you were travelling, or the gap was smaller than you needed at that speed.

I think Po-Po would look dimly were they informed.

IMHO, without having been there.

Just a guess that insurers have already considered this, but I have no sound view other than I'm still not fully convinced that adaptive CC is ok. Were there a prang, I could perhaps see te BiBs doing you for lack of attention whilst driving &/or driving without due care but again, I just don't know for sure what the outcome could be.
I've got it in our 23 reg Lexus NX350h and I keep 1 foot near the brake and I don't take my attention off of the road. I haven't had lot of cause to use it, though late evenings on the M4 or M40 coming out of London I have. It is no doubt a clever bit of kit B-U-T not 100% convinced what outcome(s) there could be from a prang.

Holidays are over soon.


Anyway, pretty sure you wouldn’t have a leg to stand on as these are assistance systems, nothing more and you should be in control whatever the circumstances.

Surely you'd just blame a rogue "collision avoidance system" activation - they can't be switched off on some cars (especially if in a hire car where you may not be familiar) and they are known regularly malfunction/phantom activate - I'm sure that this "(un)safety system" caused the braking event officer...

Adaptive cruise seems to work slightly differently in every vehicle I've experienced it in (which isn't loads to be fair). I would say you really need to know how it's going to react in any given situation and for that reason I'd have been disengaging it before slipping into a gap in traffic like that, especially if it wasn't my car or I wasn't used to it.

I've no experience of accidents caused by driving 'aids', but I would think that if car behind had slammed into you due to your involuntary brake check, you'd be on the hook for fault and maybe even failing to have proper control of the vehicle (whatever particular law that would breach) if it came to police action. At the end of the day the responsibility for what the car is doing ends with the driver, and while there may be a case that the person behind should leave a bigger gap, nobody is expecting someone to pull in front of them (in what sounds like too small a gap) and then slam the anchors.

I know a lot of people don't like ACC, but I think if used properly and not as some sort of low level self-driving feature that allows you to put your focus elsewhere, it generally works really well.

I don't know where I got it from but I thought that it was always the fault of the driver behind if they crash into you - regardless of the front car slamming on the anchors.

(Isn't this how the "crash for cash" boys get their payouts?).

No not at all. The fault is decided on the facts of each situation. If someone pulls in front of you with inches to spare and immediately does an emergency stop, how could that be your fault? And specifically I am talking about "driving fault" not what an insurance company might choose to do in the circs.

I'm one of those. It turns many drivers into more brain dead mlms than they were before.

I think that’s a good rule to bear in mind, but if someone pulls into your lane ant a close distance and immediately brake checks on camera, then I have to think you wouldn’t be judged to blame.

The gap was sufficient to safely slip in and out of safely allowing the overtaking car to pass but I think you are right when you suggest the ACC was set wrong and that setting up the ACC is my responsibility.

I can tell by how guilty I feel I carry a definite element of culpability.

So what should the OP have done differently? How would he have known that the car would suddenly whack the brakes on?
