I will mostly be keeping my upcoming Model S at a parking garage here in NYC. Like most garages, they keep the car keys hanging in the office. The garage is very kindly offering me an assigned space with an 110v outlet (I usually only drive the car on weekends so charging time shouldn't be a problem). However - if the spot I get is close to the office, it seems like anyone will be able to get into my car and drive away, any time, with our without the keyfob on their person. Correct? That seems like a major, major issue. Is there something I can do to fix this? Also, is there anything else I need to think about with regards to this situation - ie, is the car always "on" in some form when the keyfob is in range, or is it in the same state whether the fob is in range or not?
