Remote start. Seat heaters. Drive through fast food and banks. No wonder people have gone soft, not to mention there is an obesity problem in this country.
Let the truck warm up?

You will not get a "general consensus" on this. All I will add is to ignore answers from people who live in climates that don't see temperatures below 30º F or people who park their vehicles indoors. They simply have no clue what snow and ice on your windows is or even frost that needs to be removed. Neither of those are happening in 30 seconds, 2 minutes, etc.

When started in cold weather my 07 Corolla would almost immediately run up to almost 2K for several seconds. I always wondered about that since we've always been told that engines suffer the most wear at startup.

I don't see the problem

Well, not really, not if you take an extra 10 seconds to scrape the whole windshield.
heck, that frost isn't even all that thick.

Maybe a vacuum leak? Can't image reving a stone cold engine to 2K at start up is doing it any favors.

This is Normal around here, still doesn't mean you need to idle a half hour (unless it takes that long to scrape)

It's 100% normal. It's called "cold idle".

I can imagine 1200 or even 1500 rpm but 2k seems high.

Pfffft, start it, put your seat belt on, tune the radio, and go. About two minutes is enough, right ? Three to four tops !

I'm sure I can find an example with thicker frost or even snow and ice to make the point clearer to those who think you can let a car run for 2 minutes and go. I mean, you live in NH so you will understand this perfectly well.

Does it really matter how warm your oil is when your tires are frozen to the pavement?

Obviously too young to remember carburetors and automatic chokes. It's completely normal and doesn't hurt anything.

Who would be foolish enough to live in an area like that without a garage?

I may not have read every post on this-- came back several times.
I think it's a waste of fuel and hard on other parts of car but don't quite understand comments about washing DI engines with gas. To me, there should be no difference to the engine in warming up and driving slowly. Can't imagine an engine would be hurt by this, just fuel waste and uneven warming up-- warm engine and cold transmission and wheel bearings.

I remember, but there was an entirely different reason it happened with a carburetor. Now with fuel injection and the RPM being controlled by the ECM there's no reason (at least in terms of fuel supply) to need to rev in order to pull that much of a vacuum.
Why does a cold engine need to run up to high idle before the oil is flowing freely? I don't disagree that it didn't hurt anything, because that car had 178k miles when I sold it and it ran as well as the day I bought it. I just wonder what the need is.
