Exactly. The FerrariChat post mentions that after a certain pressure, thicker/colder fluid (oil) doesn't flow any more, which may well be true (I'm not big into fluid dynamics, sorry), but what is that point? I'd guess it would be above idle somewhere. Combine that with the other important stuff that needs to warm up, and we arrive back at the original conclusion to not let your car sit and "warm up".
And wait a second. The world
isn't flat? Consider my mind blown.
