Try to go completely without touching any door for a full day, nor have any passenger touch any door. With automatic doors enabled, you can open the driver side door anytime with double-pressing of the top of the keychain. Do another double press, and it opens the passenger side (only after the driver side door opens). Triple press the top to close all four doors and the trunk, that is always fun (just remember to disable single-press to close all doors, otherwise you'll probably do it by accident). When in the car, don't close the driver's side door, just use the brake pedal to close it. Use the screen to open/close doors from inside.
The "press the brake pedal to start the car and close the door" is addictive. Whenever I use another vehicle, if I don't remind myself enough before getting into the car, I naturally press the brake and then wonder why my door is still open.
