Entire car, when its sitting still? The only things warming up are the engine and everything directly connected to it such as the transmission and exhaust. The tires, suspension and other moving parts aren't warming up at this stage.

Your explanation does not make a whole lot of sense to me. I'm thinking the reason for not allowing the car to warm up has more to do with emissions/carbon build-up or something similar.
