I had the most random thought; say it’s a hot day, and you park in your garage; would it be possible to turn on the AC to help cool down the garage and maybe the adjacent rooms as well?

No. AC moves heat from one place to another, in the case of a car, from the cabin to outside. In a garage you would just move the heat from in the cabin to in the garage, adding a couple of kw in the process and actually overall adding heat to the system.
You need an AC system setup to move heat from your house to the outside. A car isn't it.
You should also probably remove your -actual- address from your profile. Its meant for a general area (Fremont), not your specific house address.

what if you run the car on a dynamo so it generates electricity to charge the car. free charging forever!
It’s possible, but not without some extra effort. As noted above, the car’s AC moves heat from the air entering the cabin to the air moving through the lower part of the car’s nose.
So the do what you described, you’d need to set up ducting from outside to the front of the car and back out again. It’s an option for extreme situations, but probably not worthwhile for the typical user and circumstances.

The Model Y could theoretically do this by turning up the interior heat.
That of course would be temporary, and would begin reverting as soon the interior of the Y reached some maximum heat capacity where the heat pump could at best keep up with outward radiation from the Y cabin. But then the laws of thermal dynamics, "you can never win, you can't even break even, only the House can", means moving heat around is always temporary to some extent.

Seriously had to explain why this wouldn't work to my father-in-law about 5 times.
I once went to a local cheesesteak plate and the guy had 4 window ac units inside, on tables running at full speed. It was hot in there.
I didn't tell the guy that this was a stupid idea, but I did laugh at the situation.
Only if powered by wind turbines on the hood.
Reminds me of the old "If I leave the fridge door open can I cool off the kitchen" 2ed law of thermodynamics question.
Wait a second, so you're telling me Homer Simpson lied to me about living in the refrigerator?

I assume from your question that your home doesn’t have A/C. Only one person mentioned your best option which is a ductless heat pump. They seemed to think that cooling the garage was your goal. That wasn’t my impression. I think I paid less than $3K for a single unit installed.
Truly hilarious! I'm trying to guess what state...Texas and Louisiana are my picks.
Haha, you're right. I re-read the OP's comment, and it seems clear he does want to cool off his place, not his garage. I self-installed a 4-unit 36k btu LG mini split. It was about $5000 for the compressor and 4 head units and line sets. Not the easiest DIY project, but also not the hardest. Had a professional vac the lines for $200.
