I've never seen this "for real", but I have read about it; basically what you described is correct... the driver has a micro-scooter that folds up small enough to fit in the boot (trunk) of your car; he'll pick your drunk self up from whatever pub/club/restaurant you're at and drive you home in your own car! Then he just gets on his scooter and goes to his next job!! And as I recall it's not TOO expensive.... price of a normal cab fare plus £10-15 (maybe $20 or so) worth it to keep your license huh?

Hope this helps
