for the second time my model S and i are stuck on top of a mountain. plenty of charge, that's not the issue. but the car won't 'see' the key. which is odd, as i can see the key just fine, it's in my hand. and look, there's the second key, in my other hand. i hear tell of key signals being blocked by rf frequencies? sorry to state the obvious, but any car, let alone a super fancy rocket ship car like the model s, shouldn't just stop working arbitrarily. especially not at the top of a mountain, 2 hours from the nearest town. as mine has done. again. tow truck is on it's way. but i might just push the car over the cliff and walk home. suggestions? thoughts? lawyer recommendations? thanks.
