I’ve read numerous articles that “warming up” a car for the engine’s sake (as opposed to heating the interior) is not necessary for modern engines. If anything, long idling periods might also put unnecessary wear on the engine and seals.

The best way to warm up a car is to drive it.

I’ve had a car guy tell me the opposite-driving it before lubricants warm up is bad for cars.

My 2011 Cadillac warms up pretty quick so no need to wait on it, just start and go. My 2004 Dodge Cummins 2500 PU is another story. Since diesel engines don’t build up heat like a gas engine it takes me about 10-15 miles of driving at freeway speeds before I can turn the heater on unless I let it warm up in the driveway for 30 minutes. Last week when we had single digit temps it was brutal leaving work heading home.

If they're anything like me, they're not 'warming up' the engine. They're waiting until there is heat coming from the vents, because they want to be warmed up.

Not necessary....but it sure is nice to get into a warm car. I have leather seats...Upstate NY.

I'd guess...the person wanted a warm car interior.

Period.
