If you come into your garage with the turbos spinning at anything greater than idle, you must have a very large garage, driveway, alleyway or high speed residential street. If you're turbos aren't liquid cooled, you are driving something older than 20years. There are two twin turbo V6s in my garage. I shut them off as soon as they are put in park. As quick as a turbo spools up, it will spool down again...a few seconds at most.
Anyone else turn everything off when you stop the car?

I fixed a GMT800 with the same issue. Initially thought it was the pulse board in motor but turned out to be the wiper switch. The pulse board was also bad because at first the wipers only worked on high.
I kinda suspect a bad pulse board toasts the switch or vise versa -- can't prove that, however.
No. In modern vehicles you have the illusion of control but in reality you are just sending an input to a computer which will determine the output aka when something will or will not happen. Just drive it.
That only happens if you are driving a 40yr old car. Most anything newer the ac is controlled by a computer and it wont let the compressor come on until the engine is running.
All off. A/C off 2 blocks from home.
Fan, wipers and AC off.
On a hill: I set the parking brake set with car in neutral, release brake to let PB hold the car, then shift into park, 1st or R.
The radio is never on because I don’t listen to it.

Only wipers and lights because my RAV4 since it’s a base model doesn’t have automatic lights. Everything else stays set exactly the way it is and I never change it. Radio stays on and on the same channel at all times when operating and air/heat stays on. I know one guy who cuts everything off when he gets out and it drives me insane lol. I need the air blowing on me as soon as the car starts not 30 seconds after when you turn it on.
You don’t disconnect the ground cable as well?
Shame!
Own a bunch of old beaters, with switches for just about everything. Been shutting down all the accessories since the 70's, and never broke that habit. So, yeah. I shut most everything off before I shut down the engine. Also flip up the wipers before a snowstorm to make it easier to clear windshield.
I shut down a/c a mile from home in hopes of drying things out. Doesn't work, once it gets whatever mold in there, it's seemingly there going forward (or I've not used the good stuff to kill it).
I love the fact that my Corolla is smart enough to buzz at me if I take the key out with the headlights on... but not actually turn the lights off. ? Like, they could have easily fixed that, but no, this is how they shame you when you buy a cheap(er) car. Regardless, in general, lights, wipers, a/c off. Radio though I'll leave as-is, but I usually drive with the radio off anyhow. [But on this Corolla I got into the habit of turning the radio off as it would kill the battery. Not sure there was a fault in the radio someplace but I did have a bad battery that finally stopped holding enough charge overnight to start.]

Do you not have auto climate control and remote start? It's a death sentence in Houston without it.
A friend in NZ had a JDM Mitsubishi turbo diesel van. After the ignition was turned off, the engine would continue to run for another minute or two so as to continue to supply oil to the turbo while it (the turbo) was spooling down.
Jeeps - if it was raining I turn the wipers off. BMW and LR3 are auto wipers. Otherwise don't touch anything. Sometimes I'll adjust the climate control up or down so it's set right for next remote start session. If it was snowy/icy but won't be next time I drive, sometimes I'll put the Wrangler back into 2WD as I pull it in.

I even turn off the engine too 
Remember - the a/c system is a dehumidifier. Ever notice pools of water on ground after operating a/c system? This is reason a/c compressor runs when activating the defroster. Removes moisture from inside windshield
Modern cars are designed to operate (start and stop) without much driver intervention. There is absolutely NO practical reason to turn components on or off (outside possibly the wipers if doesn't have rain detection). Doing otherwise only means you don't have enough more important items to occupy the grey matter. You might seek medical help.
The only time I would consider a idle cool down is if you are finishing hot laps.

I drive a bunch of caveman vehicles with manual controls so I frequently turn stuff off. Its more for me than the car or truck. Not a fan of a blast of hot or cold air in the wrong season, a screech of the radio blasting some 80's tunes, or a smear of the wipers when there is no juice to lube/clean the windshield.
Why stop there? Probably should raise the car onto jackstands, and drain the coolant and oil also.
I actually bring the engine inside, so it's not outside or in the garage dealing with extreme temps.
Never have , never will .
