You'll have to forgive me if I believe the experts at the car manufacturers, Liqui Moly, Shell, and Esso over a random "mechanic" on Reddit.

From Consumer Reports:

>Modern cars have improved on technology to the point that your engine is fully lubricated within 20 to 30 seconds. By the time you get in, start the car, put on your seatbelt, and get situated, the engine might not be fully warm, but it’s completely lubricated and you’re okay to drive at this point.

A lot of what I've read says it's harder on your engine to idle when it's cold than to drive easy. In part because the lubrication gets spread around sooner.

Edit: And let's make sure we're talking about the same thing. I'm talking start your engine, and then start driving normally within 30-60 seconds, vs starting your engine and letting it idle for 10-20 minutes.

I did it at least a few times a year when I lived in Fargo, ND. Just drive easy until the engine is warmer. The engine warms up faster when you're driving than it does idling in the driveway.

Yeah, my mom is 20 miles outside of a 3000 person town. She pays $50/month for 200mbps (Gbit is available). That's less than I pay in Minneapolis. Internet availability and pricing makes zero sense.
