No, not a service where drunks drive, but a service that drives those who are drunks.
My bro-in-law told me about this yesterday. Apparently, they're the big thing around the bars in Louisville. These guys wander around with folding motorscooters. If you've had to much to drink, they will (for a fee, naturally) toss the scooter in your trunk, drive you home in your own car, then take the scooter out and go on their way. Much better than calling a taxi, since you don't then have to get a ride back to your car the next day.
Anyone else hear about this? Seems like, in cities without a lot of sprawl (where it wouldn't take you an hour to get back downtown after dropping someone off) a folding bicycle would do the job just as nicely.
