I'm torn here. I can understand both sides.
Sometimes, I'm cleaning the car, plugged in, HVAC on, BT connected, because, quite honestly, I want to not sweat/freeze in the car as I make it pretty and love the sound. I've also left a thing or two in the car and don't need BT/HVAC.
One thing I can think of is using the app and deep sleep function here. Tesla engineers/programmers could design a 'continue sleeping' option on the app. Allow a time of say five minutes where the car is unlocked but otherwise sleeping. No HVAC, no BT, just quick in and out. I am not sure any other programming works, unless maybe utilizing the sensors in the seats to prevent activating HVAC/BT capability if not in use. However, I, for one, use the auto connection on door opening to play music. Possibly, put all these as options in the UI.
