Does it work better when you use the key fob from inside the car? I would expect that because they surely tested a "unlocked accidentally and locked again right away" kind of scenario.

At least on ours, it tries to maintain the invariant that all doors lock at once (for aesthetics?), so you cannot lock anything if any door is open. It also likes to auto-unlock, but not auto-lock when you’re outside the car.

If two people lock it at the same time, it locks, then unlocks.

The smart lock stuff on it is even worse. I didn’t think it was possible to screw up car door locks so badly, even knowing Tesla’s implementation burns people to death sometimes.
