This might be common knowledge but, after about 800 motorway miles recently, I've just noticed something that the ACC does -

 

If running at, say, 70 on ACC and you approach a car in front doing a bit less the car will slow to match the one in front. (You're all saying "we knew that")

Sometimes you can't swing out to pass the one in front due to traffic passing you in the fast lane. (well, doh!)

So you wait for the faster traffic to go by and indicate to overtake. (doesn't everyone?)

 

What I just noticed is that the ACC responds to the indicator use and starts to reduce braking (if you are not yet down to the speed of the one in front)

or to speed the car up a little in anticipation of pulling out into a clear lane and resuming the speed set on the ACC.

I like to think of it as "taking up the slack" just before the way in front is clear.

 

As I said, I might be the last one on the planet to notice this but I am pretty impressed that someone though to code the feature into the ACC software.

 

I've had the car for six months but I'm still finding out how it works!

 

It's like added encouragement to signal before changing lanes. It's quite noticeable if you are in Sport or have your Individual mode configured to ACC/Sport acceleration (sorry, I'm not sure how to phrase that clearly – it's one of the options.)

Will have to try the ACC on sport, I'm guessing vs Eco it's pretty brisk in getting back up to speed? 

 

Also indicating when you've got active lane assist in is pretty much a requirement or else the car physically resists the change of lane 🤣

It's good isn't it.

Yep, it's good. Took me a while to learn/be aware of this feature. Agree with earlier post, it is a lot more noticeable on Sport vs Eco mode.

It is a nice little touch to have. My Citroen has ACC but doesn't do this so when you pull out it takes an age to realise that there is now nothing in front and to give it more Gas. The Superb system is a step up from this.

Yes, it definitely does that. The other fairly clever thing is that is not just concerned about how far you are behind the vehicle in front for a particular speed, it also takes into account any speed difference. So for example if a car overtakes you with a fair bit of excess speed, and pulls in a bit abruptly, the car doesn’t slow down because it knows that in a couple of seconds there will be adequate distance and in any case the speed differential adds a braking safety margin. Ditto if you wait for a car to pass in the outside lane going quite a bit faster, then pull out behind it pretty close, the car doesn’t flinch for the same reasons. Yes, it is quite well designed.

Sometimes drivers acc does not recognize the drivers that have changed to slowing lane, so it tries to slow down when there is no need to do so, i i have to mash the throttle to override this. Most of the time it does work like it's supposed to, the lane changing thing seems so intuitive that i haven't even thought of  this as a separate feature.

So it forces you to indicate, possibly unnecessarily, in order to avoid wrestling with the steering?

 

I don’t think I’ll like ACC in next car.

ACC is bloody awesome. 

 

And 'wrestling' is a strong word, it resists you moving out of your lane, as active lane assist should do. You can always turn it off and still have ACC. 

 

Really isn't an issue to flick the indicator when you want to change lanes. 

 

Motorway driving is soo easy with ACC and lane assist, you don't have to concentrate so much on tiny steering adjustments to keep in your lane and can pay more attention to cars around you, reading the traffic etc.

No you are confusing ACC with lane assist. If you have lane assist on, you need to indicate to temporarily disable the lane assist to avoid “wrestling with the steering”. ACC does not resist you changing lanes.

 

Anyway, why would you not want to indicate when you change lanes? It is required by the Highway Code and good driving practice. If you only indicate when you think there is someone to indicate to, what happens when someone is somewhere not expected? Or are you perfect and the only human being to never make a mistake?

I'm a huge fan of the ACC / Lane Assist / Active Lane Guidance combo, for all the reasons above. Another one I'd throw in the mix is the Blind Spot Monitor. Put them all together and it's a massive help in maintaining awareness of everything that is going on around you. I have subtly changed my driving style as a result of having these features (I put up a thread about it a while back) and I can't see myself ever going back to a car without them. And ACC in "Sport" is great .

Here's another subtle one I noticed last night when stuck in traffic.

 

I always stick on ACC in a jam but noticed last night that every time I came to a stop the engine cut out as "Start/Stop" was on.   When the car in front started to move in the slow traffic, the engine clicked back on itself, without me having to engage either the accelerator, or as i tend to use, the ACC stalk.  At first I thought it was just coincidence but it must have happened about 10 times.  

Very clever!

My car does that also. It's actually quite annoying when the traffic is at standstill but that one car in front decides to creep along just a tiny bit. My car sparks to life all excited to go, but nothing, just a false alarm...

 

The Start-Stop feature on automatics just kept driving me nuts, but my current superb is manual and the start-stop just takes the same time to start as it takes me to clutch in and select gear, that actually works out just exactly right, so the complaint above is the most i can manage. In general I'm impressed how much i actually don't hate the start-stop.

 

Just as a regular user observation from a guy who has used regular cruise controls for the last 15 years: no way in hell I'm going back to regular cruise control, it just can't be compared. 90% of the time i just cant be bothered to overtake the unstable arse in front. Just engage ACC and change gear when needed, that it. The downside is that i have become more used to it and expecting the car to do this for me, so i pay less attention to the distance with the car in front. Not a pleasant surprise when i drove my Missus Mk2 superb last time...

Yeah mine starts the engine when the car in front moves away too. 

 

I find that pulling away from start stop in one action is a bit jerky so I tend to blip throttle to start the engine when I about to go, this doesn't disengage the auto hold, so when I wasn't to pull away a second press on the throttle releases the auto hold. 

 

The traffic jam assist can be a bit jerky at times, especially in very slow moving traffic but it's nice to have. 

 

 

I like how the ACC doesn't let you undertake unless you give the accelerator / ACC stalk an encouraging little tap

Strange, it is the undertaking prevention that tends to annoy most people.

I thought it would be far more annoying than it is, but it's not an issue really.

+1

it definitely annoyed me a lot!

glad the feature could b deactivated

I think it’s a smugness thing as we have a smarter ACC system than Golfs which will happily sail past people on the wrong side cos it’s ‘basic’ 🤣

Bugged the heck out of me!

 

Turned it off using VCDS as soon as I found out you could! Filter lanes & where motorways split & join etc. were a total PITA!!!
