Welcome to the Tesla club
I was a long time ICE enthusiast as well! I have had a 69 convertible, 79 Bandit, 87 GTA and 93 Pontiac Trans Am WS6 (the 69 was a tribute, I named him "9 of 8"). Pontiac was my brand of choice back in the day. I can definitely appreciate your love for some good new I guess? Muscle cars. Very cool.
As for things to learn about MSPs... I think I would go with just learning auto pilot, paging through the menus, and making my kid's seats fart lol. Did you get FSD, or EAP? I went with EAP, which I really enjoy. Summoning your car in a parking lot is a great parlor trick, and so is lane change on the highway. NoA is also nice.
O yes, also do a launch. Make sure you are in a safe place, preferably a dragstrip, but push it as you see fit. Just put it in the mode, let the battery prep, and give it a go! The instructions are self explanatory in the car IMHO, it is simple. Also, have the car do a dance! Those can be selected in your toybox. There is so much in there, explore the games. Also, put a PS5 or Xbox controller in the center console for the kiddos. If you take road trips that will be fun to occupy them during charging (though we charge very fast now). My son is all about Cuphead.
Tesla Acronym list (in case you have not seen yet)
MSP - Model S Plaid
NoA - Navigate on Autopilot
EAP - Enhanced Autopilot
FSD - Full Self Driving
Above all, enjoy! I am right there with you too... save the planet? na, it is cool and all, but I am not too worried. 1,020 Horsepower car that costs less to drive per mile than a Prius? Yes please.
