also, don't let the car warmth clean your windows - get a scraper. otherwise you are just wasting gas.
I'll start the car, get rear defroster on, and then start scraping ice/frost off windows. If it takes a few minutes to scrape, the car warms up a few minutes. I'm not starting it and walking away to let it warm up and clear itself.

I am speaking about cars in general. The M3 lives in the garage and doesnt go outside to play in snow or ice anyway.

I wait until the cold start no longer sounds like a lawnmower. Around 15-20 seconds.

I don't let the revs go past 2500

5 seconds. This shit is alien technology, no need to warm anything up!

My fast idle slows to normal in 30 seconds...takes another minute or so for the wastegates to close and the exhaust to quiet down.

I do the same thing. ~4-5 mins before sport, and another few after that before sport+. Basically sport+ only when oil is 100% up to temp. On the shutdown side I usually put it into efficient mode for the last minute or so before parking to let the turbos take it easy. I am 100% we dont need to worry about any of this, but do it anyway.
The irony is that Sport+ uses additional cooling and drops your temps faster than Economy or Sport, cooler oil cools turbos better.

Start it, go back inside for approximately 1/2 an hour, return and drive
