Warming the engine by letting it idle in the driveway is not a smart idea.The engine doesn't operate at its peak temperature, resulting in incomplete fuel combustion, soot deposits on cylinder walls, oil contamination, and ultimately damaged components.

Should not leave the cold engine at idle. I usually wait about 30 seconds, if it is sub-zero outside, before driving off slowly. That gives the oil time to flow throughout the engine before driving. In warm weather, I just wait about 10 seconds.

I have a friend who majored in Mechanical Engineering and focused on combustion engines. He tells me to not even wait a bit. Just drive off after starting the engine, but remember to keep the RPMs low for about a quarter-mile or so, until the engine reaches full operating temperature. He gave me some engineering mumbo-jumbo about how the oils won't be properly lubricating components unless the car is moving and blah blah some other stuff. I forgot it all. I just do what he told me to do. 
He was telling me that idling to warm up is a bad idea.

Waiting for W204 Facelift
I think MB latest cars DO this itself automatically (with turn the key to second position before engine start light off all equipments on the screen and it means it is ready to start )

I don't know about stuffing a rag in the tailpipe, some of the stuff on there is strange, but for sure the warm up procedures seem reasonable.
