i agree. i dont see any benefit from idling the car for some minutes to "warm up". what i normally do is wait a few secs, enough time to buckle my seatbelt, check mirrors, etc., and just go. but at first, i put it in a low enough gear so that the rpm's are just about the "warm up" level (~1500), but still meeting the speed limit. i normally hit a couple of stop lights anyway, so my engine's "warming up" while i'm sittin there.
