I posted this on a couple facebook groups this past weekend and thought it was appropriate to share here as well. I travel for a living in a M3LR and often use destination chargers. I'd hate to think that I'm keeping someone with a lower range car from charging if they needed it. So I got out my label maker and printed a label with my mobile number on it. It's under the charge flap so it's protected from the elements and is only visible when I'm plugged in. The beauty of this is that most destination chargers have a long enough cord to reach another parking space... so it's just a matter of me remotely unlocking... I don't even have to get up to release my charge plug.
