Hm, that's strange because my friend, who owns a Tesla, said that before he bought, he was given a Tesla to drive for a weekend. So not sure what you're talking about.
Here are some tips:
Make sure front seat belts are not clicked in. May think someone is in the vehicle and keep HVAC on
Turn off proximity entry with the phone
Turn off Gear Guard (completely or only at home)
Make sure you're updated to the latest software version
The next "big deal" is when you get your own home charger and never have to go to a charging station. Always be topped off ready to go after you wake up in the morning. :D (Assuming you don't already have one)
TBH, learning this should be VERY easy. I learned this while driving home with a new vehicle. It has basically become a game now to see if I can time the regen braking to stop right before the stop sign or light
