Is this a joke? That's the worst thing you can do for a car, especially running A/C. Letting it idle for extended periods of time is terrible, carbon buildup being but one of the issues. Maybe in 1935 that was a prudent measure to take....
As for me, I just let the idle come down and then drive it easy until temps get up.

I start my car and put it in S+ right off the bat. Get engine temp up to 140ish and then casually hit the road. Spirited driving begins once the engine and oil is at normal operating temp.

What about reaching optimal tire temperature for road adhesion?

Remember that virtually none of the engine ancillary functions (cooling, oiling, etc) are - these days - purely ‘mechanical’ or ‘electrical.’ Warm-up will happen at the fastest rate that the software allows regardless of mode. This will happen for a number of reasons.
Engine LOAD is far mode important to moderate during warm-up than is rpm. Or, IOWs, flooring a cold engine from idle to 4k rpm is worse than going to redline at 1/4-throttle, though both should be avoided.

Guys - so for my 991.1 manual, if I start up, buckle up, wait 30 seconds, move off and keep revs and speed down until both oil and water temps are good, all will be well?

There’s no point in “waiting” but if it takes you 30 seconds to a minute after start to get everything situated (e.g. sunglasses, belt, music, etc) it’s fine.

I have heated garage flooring and heated blankets wrapped around each tire in the garage. It does drive my home electric bill up, but as you note, what good is a fully warmed up engine if your tires are cold?
When I lived in North Dakota I had an engine block heater on my cars due to the extreme cold. You'd plug your car in at night so your oil stayed warm. Without it, cars parked outside would not start/not start easily. Anyone know of a good source for a 991 engine block heater? The dealer doesn't carry them and the guys at AutoZone scratched their heads as well. If I had this, I wouldn't have to let the car idle for so long to get the temp up.

Works like a charm and on snow days the tires clear a path right to the asphalt.

Living in Ontario I had the exact same issues but found the blankets were simply too weak so I purchased 4 Dyson AM09 heaters (I have 20" wheels) and attached them to the garage floor at the optimum distance from each wheel and simply left them on overnight.

Those things are sweet. Please confirm that due to the strength of those heaters, you somehow bolted them to the floor for safety as well as not to be accidentally shifted and damage the paint on your car. This has potential for an upcoming Panorama/Excellence magazine.

When it comes to Dyson there is no substitute.
