Is it actually bad for the engine? I presumed that stressing a cold engine while driving is worse than just letting it idle. I have a 2018 car and it gives a warning light if the engine is cold. At the very least it makes scraping take half the time.

Yes, according to the manufacturer of one of my cars, idling the cold eninge should be avoided - considerate driving quickly after starting the cold engine should be considered instead.

The argumentation in the manual is that the car won't reach operational temperatures for a longer time while idling. New efficient motors apparently idle very efficiently (surprise?), which generates not enough heat.

I see. My old 2000 acura would idle another 1000 rpm higher when it was cold, maybe to warm it up faster. Some new cars seem to shut off completely at a stop until you hit the throttle.
