We have something like that in Syracuse..... Its called SMART...... You have to pay to be a member but you get a number to call if your trashed somewhere and they send a car to bring you home...... but yours stays.... SO when you wake with that massive hangover, all you have to do is remember which bar you left it at and call a friend to drop you off...... Oh I suppose you must also have to remember where you threw the keys after you got inside the house......lol I usually leave them in the lock!!!!!
