Anyway I get your point. It is certainly wise to put the vehicle to N whenever possible.
No worries, now I'm on another dual-clutch, and I get stuck in jam most of every working day.
I understand your point. If it stop start every 1-3 seconds, I don't shift to N also. I just keep in D. But some point to take note for this:
- Once let go brake, must step a bit on accelerator. Do not let it "ride" the cluctch to crawl/creep. If you "ride" it... it is the same as "riding" the clutch-balancing on a manual in traffic jam. Clutch does not engage fully and this will boil up the transmission oil in dual-clutch. It will be worse if it is dry gearbox, heat up faster since no oil to disperse the heat.
For manual car, it will wear out the clutch plate very fast. FYI, I used to drive manual car (yes, stuck in KL city centre traffic jam - Jln Ampang, Tun Razak, Sultan Ismail - nightmare area) and my clutch did not wear out after 9 years, even the mechanic says my clutch is still good when I sell it.
Another question I want to ask is ... when he is doing this ... is the road quite flat ? or going uphill slope all the way ?
But for stops of 8-10 seconds or more, try to shift to N.
BTW, if the car can creep/crawl every 1-3 seconds, I don't call that traffic jam
I only manage to creep forward once every 3-5 minutes, and it can take up to 60 minutes to travel 100m
