I give no fark for wasted fuel.

If I was worried about economy I'd drive a hybrid.

The point of the argument, which you seem to be missing, and I keep needed to repeat myself about is that when you warm your car up for any longer than a minute before driving off, you are causing so much more wear to the engine than simply getting in, starting up, and going, while not revving hard until the engine is warm.

The secondary effect, like we keep telling you is that if you warm it up, the engine is warm but every other part of the car is cold, and you think you're right, but you will break stuff .

I've experienced it first hand. A mate with a WRX let his car idle for 5 mins to warm up, then when he took off, boosted it all the way up to the limiter, changed into 2nd, and the gearbox disintegrated.

That's the risk you take.
