Hi. just wondering what happens with a model s if you park it in a parking garage (think apartment) underground where there is little to no reliable cell signal for the car. obviously the app communication to the car would not work but does the car keep trying to acquire a signal like a cell phone? does this mean the car when not plugged in (since I can't do that all the time in the parking garage) will lose charge faster since its going to keep trying to acquire a signal? thanks!
