Collision avoidance fail?
Discussion
It's a worrying thought if you're in a situation like the OP, joining a motorway from a slip road and traffic is zip merging.
I can see a situation where the car you're looking to tuck in behind overreacts to the car joining in front of him and anchors up leaving you driving into a now non existent space.

Have just had the displeasure of a new Tiguan for three weeks, it did something similar to me 3 times in those three weeks. Massively over reactive & on two of those occasions positively dangerous imho & I work in the industry testing & demonstrating this stuff.
It appears to get confused, especially when surrounded by other vehicles, I assume its a radar bounce back issue off of other vehicles that should not be a concern to the system - BUT IT IS
A truly awful thing to drive anyway so just avoid like the plague.

Hypothetically, if this caused a collision, could VW be responsible perhaps?
The person who ran up the back of the braking car would be at fault. I would imagine we all follow too closely sometimes, whether it be subconsciusly thinking we have left enough of a gap, or consciously in order to prevent others cutting in during heavy traffic. I use the active cruise control on my Golf on the motorway, and even at the minimum distance setting at 70mph, it leaves a big enough gap for an optimistic driver to cut in. If they're braking during this manouever my brakes come on quite hard to match their deceleration creating the gap again. Edited by FlabbyMidgets on Tuesday 27th June 21:38
Its not good for smooth motorway driving where gaps need to shrink and grow. Its very much like the outside lane during busy conditions, where lots of people are in a rush and braking and accelerating, and the impact flows back down the chain, whereas an inside lane often flows faster with bigger gaps.
The collision avoidance has only ever activated once on my car, and it certainly saved me from plowing into someone else.
Its a pretty good system for "nannying" drivers, but its not intelligent enough to make judgements, only fixed decisions. The software will adapt in the future im sure.

Sounds like a good reason for staying in lane 3. At least you'll only be rammed by a car then - what you really don't want is a 44 ton artic ploughing into you.wack said:
It did once in traffic when the car in front dawdled a bit and I got closer than it liked which woke me up, I'd only had the car a week, I didn't even know it had collision avoidance
If you're someone who adopts a "synchronised driving" mode, where at junctions and roundabouts etc you're cutting things fine by anticipating what's going to happen then you really do have to adapt your driving style.Sheepshanks said:

It is positively lethal at times, cars turning off very slowly, busy roundabouts etc, it just suddenly beeps, dash goes red and anchors on the brakes, its bloody dangerous.
Adaptive cruise is great on the motorway if quiet enough, but other than that, im straight into sport to disable it if im pressing on
To top it all off i get a smack from the wife for not paying attention lol

What is it you do in the industry? Pm if preffered.It appears to get confused, especially when surrounded by other vehicles, I assume its a radar bounce back issue off of other vehicles that should not be a concern to the system - BUT IT IS

I spend my day dealing with ADAS solutions and recalibration etc.

I've driven the new mk7 and it is wonderful on the motorway, but as you said, a pain in the arse elsewhere!It is positively lethal at times, cars turning off very slowly, busy roundabouts etc, it just suddenly beeps, dash goes red and anchors on the brakes, its bloody dangerous.

I also tend to adopt the syncronised driving style, and my missus twitches or shouts at things that I've *already* factored in and was watching, but her reaction throws me off, which is bloody annoying!
