exactly, I think jjrandorin missed the key point of designating a separate valet keycard. I wouldn't tap the valet card to turn on valet mode, the valet would do that when they unlock or drive the car. I would keep my own regular keycard in my wallet.
I didnt think I missed the point, but your point was not "I want the keyfobs to link to to profiles" as I saw it. The valet profile is a special one that behaves differently.
As I said, if a keyfob was linked as a valet key specifically, I spelled out the problem I see, which is, unless you give them the key, get out, lock the car, and immediately ask them to unlock it with that key, they will be driving the car UNDER YOUR PROFILE as thats the one you pulled up with.
When they bring the car back, it would be under the valet profile, but as they drive off, it wouldnt. So, I dont think this helps your original "ask" which was specifically for valet key. Even if they activated that, its of questionable benefit from what I see, which is why I asked for you to explain what work around there would be for the valet key situation that would not be just as slow as going in the app and clicking the button.
Now, if the discussion has moved from valet keys to linking keys to profiles specifically, that I am all for (and my BMW does that already). Linking a key to a specific driver profile would save a couple of steps, or, if you are like my wife and I (6'3 and 5'6), if she drives the tesla, when it adjusts from easy entry to her profile when I get in it, I get somewhat crunched, until I select my profile.
I just dont see how it helps in the valet situation for the reason i stated.. which the TL ; DR version is, since you arrived driving under your profile, when you hand the key to the valet and they drive off, they will still be under your profile unless you make them lock and unlock the car before they drive off.
