A bit funny how some owners warm up their car at 50 degrees Celsius while others start and go below zero Celsius. So far I believe Marcus was the only one with technical evidence behind his views.
The fact that many engines "roar" when leaving almost immediately does not mean that this would be worse for the engine than leaving it idle too long. I'm not sure if it is all over EU but in my place idling is not allowed, max 2 minutes even at extreme cold.
Everybody is allowed to do how they feel best with their own car but I do like Marcus, except that I don't need to wait till the idle goes down, my diesel does not seem to have high idle when cold. Even if it had, I would let it run till oil lubrication works properly, then go. As long as the engine is cold, I run smoothly and avoid high rmp. At summer time it takes seconds to be ready to go, at very cold weather it may take half a minute.
Note anyway that the rest of the car needs to warm up too, you may get a false feeling if the engine has warmed up on idle while the rest of the drive train plus shocks etc. are not. Again better to get going relatively quickly but running carefully first, allowing all parts get ready.
Of course if there is a threat of windows getting misty, you have neglected preheating or other means (like using the garage) but have to wait till visibility allows safe driving.
