BMW has had that feature for years... its not as seamless as one would think.. at least on BMWs. The main issue is, its tied to the key that unlocks the car, but when you have 2 drivers with 2 keys that go to different profiles, the car sometimes picks the first one to open the door (as both are there).
In teslas case, I am almost sure that would happen as well, and if you have 2 drivers with pretty different driving positions due to height (like me at 6'3 and my wife at 5'6 for example), if it switches to the profile of the smaller person you have to then change it.
Worse on tesla, if you were using easy access, it would then crunch the taller person into the smaller persons seat settings. This WILL happen when tesla implements this. At least in BMWs case, they could theoretically ignore the passenger side unlocking. I guess tesla could ignore the passenger door too, but both keys are valid on starting the car, and the car is able to see both keys, so they would have to use the actual door being opened or something.
Because I have been living with BMWs implementation of this since at least 2012, and it has never really gotten much better for families where both carry a key to the car (my wife and I both carry our keys with us at all times, regardless of who is driving), I am hesitant to think this will be better in the tesla.
