If this guy can keep a Mini on the road I guess keeping a lawn nice is no problem.
Backstory: I have a couple older relatives that will start their cars and let them “warm up” for a 20 minutes in moderate 30F temps. I get when its single digits or below its best to let it warm up, but they both take it to the extremes from mid Nov to April.
I get in the days of carbs this was common, but neither have owned one of those in 30 years.

If they are pompous and cocky (especially dudes), call them out on their inability to sit in a slightly cold vehicle whenever they’re boasting.
Alternatively, mention the cost of gas.
Alternatively, turn their A/C to max cold.

This really grinds my gears too. 5 minutes max is all you need.

I’ve seen drivers I won’t describe let their car warm up until the aux cooling fan comes on before they will drive. This is in a garage in relatively mild metro Seattle. I have no words.
For the modern car, which is always garaged, I let it run until the dashcam goes into normal mode (maybe 20-30 seconds), then it’s time to go. For the old car, probably no longer than 30 seconds, then take it easy for several blocks, but not too special either.

The guidance I’ve seen for modern cars is generally not to let them warm up at all, just be gentle driving them until they are up to temperature. Just idling doesn’t warm the engine very fast at all, so apparently it’s better for the engine to decrease the time spent running cold.
The manual for my car (not so modern) says:
Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.

I used to use my downward sloping driveway to warm up my datsun, 1 minute and i could back off the choke.

This is not an accurate statement. It varies by car.
In the old days it was an issue of the car running right. These days, it’s an issue of doing catastrophic engine damage . Whoops. Turns out when we made the tolerances a lot tighter? Having properly warmed oil before applying load to the engine, kinda important .
20 minutes? Definitely too long. 5 minutes for a Hemi 5.7? Not long enough. GM LTG? However long it takes for the coolant temp to indicate a minimum 105F using Dexos 5W30 or equivalent.

If it’s really really cold(-15 & under) I let it sit for a while, but normally a few minutes is all it needs.
