Do double clutch and automated manual gearboxes creep?

Its something I've wondered for a while, but never known, I've never driven one, don't think I've ever even been in one. I hear they aren't so great in carparks, so maybe not?

Are they as good as everyone says?
No.Another problem with some of them is no Park position. So you rely totally on the handbrake.
Try a Prius instead ...

No park position? On the twin clutch units you have the usual PRND layout. I would have thought that the single clutch 'easytronic' style ones would have as well.Another problem with some of them is no Park position. So you rely totally on the handbrake.

The SMG in my M5 doesn't creep. It will change down to 1st automatically at standstill and then release the clutch so there's no drag. The brakes have a hill assist and will hold the car for a second or so before releasing. This gives the clutch time to engage and then move off.
There's no "Park" feature, and it's suggested that you leave the 'box in 1st or reverse and not neutral.

The M3 DCT will creep, but you have to tell it to with a tap of the throttle, it will also make you look a tit by rolling back by not engaging first from reverse on a hill quick enough and leave you pressing thin air whilst you stamp on the foot brake, most mornings! 
In fact those moments when you attempt to swing round in a side street but haven't got the steering lock to make it so have to engage reverse to complete the move are the times it loves to go to sleep, most annoying.

Out of interest how does the stop/start work with this?
Stop start on the M3 DCT has a mind of its own it decides whether to stop or not based upon lots of info, if the car is creeping it obviously won't stop, light braking to a stop and then adjusting the brake pressure whilst stopped tends to "stop" the stop start feature in my experience.

DCTs do 'creep' just like a conventional automatic. When you release the foot brake the clutch engages.
Out of interest how does the stop/start work with this?Not too sure what happens if you engage handbrake and put it in neutral as I only had the car overnight and just used it on a couple of short journeys, thus I didn't really test it or play around with settings. I would assume that it is intelligent enough to keep the engine off until you have it back in D and lift off the brake.
In practice I didn't really notice any delay when moving off in D vs my regular DSG box without engine stop/start but I'm sure that if you timed it, it wouldn't be as quick to engage as it would be if the engine remained running - I left extra space when pulling out at junctions to be sure.
My impression was that it's certainly a good match for an auto/DSG box if you routinely wait with the footbrake held down at lights and presumably the fuel savings outweigh any wear and tear on the engine.
I've driven a 2010 and 2013 Skoda Superd DSG and both had far too aggresive creep settings. In my old style Merc it will creep gradually and on more than a gentle incline will just hold still. Both superbs the creep was far too fast and engaged quite aggresively.
On the move they are fantastic but still not as smooth or well executed as a regular auto imo.
Dave!

I'm guessing though the older Merc was a conventional auto so not worthy of comparison with a dual clutch.....Double clutches and asm's can creep, but its only the same as you slipping the clutch in a conventional manual. So it can for a bit then will just overheat and fail, old wet clutch dsg were better but dry ones aren't much better. Its one of the biggest issues as overheating makes them fail open and you loose all drive, so creeping in hot traffic is a big issue!
Neither box traditionally has a mechanical park like an auto, in fact don't know of one that does, so rely upon the handbrakes like a manual in neutral
