It doesn't select neutral at standstill once the engine is warmed up after a cold start. Personally, if I'm stopped long enough to engage the handbrake, I stick it in neutral; if I'm just pausing with a foot on the footbrake, I leave it in drive.

I move to N too, it just 'feels' wrong to leave it in Drive to me because you're in effect holding something back against it's will, which will always generate heat.
That wiki link does say it can select neutral though.. However, on the occasions where I've left it D by mistake for more than a few seconds the car has always pulled away immediately when it was time to go - if it had selected neutral surely there would be a delay?

BMW call it NIC (neutral idle control). From their documentation:

This sounds alien to me, how is neutral any different to a gear being engaged but with the clutch plates separated? my car certainly doesn't feel like the brakes are fighting an engaged engine when stationary in D mode?
EDIT: in the manual it just says: "N Neutral You can select this in a car wash, for example. The vehicle can roll." You'd have thought if the N setting should be used whenever stopped, it would be mentioned with priority over "when you're in a car wash"?

Like Sootylad says mine doesn't feel like it's pulling against the brakes when sitting in drive, In fact it feels like the engine is disengaged from box whether engine is hot or cold! And I would say there's definitely a slight delay albeit for a split second when cominig off the brakes and it engages again to pull away!

I also mentioned this earlier in the thread but this seems to have been ignored. I have heard this from several sources including mechanics which is why I don't do it.

Most of my driving is freeway but everytime I stop for more than a minute, I have always shifted to neutral to minimize force in the tranny. Lately, since my front brake pads are low I tend to put it in neutral more often to relief my foot from the brake since i have to puch harder. My handbrake works great!

No excess wear will take place with running the transmission in N rather than D other than normal bearing operation. I can't produce 'evidence' per se but then neither can these pub car experts |
