I was thinking about the key fob as I replied in the "what's going to fail first" thread. The Tech Package is supposed to detect my fob as I approach the car and do magical things to unlock, extend handles, and personalize the car for me, right? (meaning, I don't have to press any buttons on it). My wife's also going to have a fob too, it'll be in her purse. As we both approach the car, which fob will it personalize for? Maybe the car should pick one of us at random, and whoever the car chooses gets to drive . Certainly this is a "solved problem." How is this handled in other cars with keyless ignitions, like recent model hybrids? How should it work on the Model S? /Mitch.
