Haven't read the entire thread, so apologies if these have already been mentioned, but here are some of the less-talked-about benefits I love:
1. No need to go through the sequence of "shift to P, turn off the ignition, engage parking brake, lock the car" sequence when you arrive at your destination. Just press "P" and walk away. The car takes care of everything else. On level ground, with "creep mode" turned off you may not even need to press "P".
2. One-pedal driving (most of the time). This gets talked about to some extent with EVs but I really do find it much more convenient than two-pedal driving.
3. Being able to set the AC to come on automatically when the cabin gets too hot. You don't need to remember to turn on the AC when heading over to the car (or worse, get into a scorching hot car).
