New suggestion, minor peeve that gets me every time I approach when the car is locked: the little catch when I pull the handle on the door as the car is unlocking itself. It almost always opens, but not before resisting for a fraction of a second. It's a constant reminder that the tech is not actually seamless, but has a little hiccup. I use it as a reminder that this car is fallible, take a deep breath, something's not going to work as expected.
As a comparison, if I am able to unlock the car first, the door opens smoothly, so I know what it's supposed to feel like.
Just fix it. Start unlocking a half second earlier. Make it smooth.
(this is with the iphone unlocked and the app active, all settings maximized for connection, tried debugging every way, don't need any help with any of that).
