The Beer Bicycle

So, with Oktoberfest at a close, I discover this answer to drinking and driving:

Yes, it's a beer bike.  You rent out this contraption, have a bunch of your friends pedal the thing, while another (sober) person steers it, all the while touring the city of your choice as you all drink beer on tap.

Those Germans think of everything when it comes to accommodating Oktoberfest.

The city of Dusseldorf has decided to forbid the use of these beer bikes (you can't use them without a permit in Dusseldorf), not because of the drinking and driving issue, but because they're slow, and some passengers have fallen off and obstructed traffic (no one killed, though).

No, I have not tried this thing, partly because I'm not sure how many people I can get to go in on this with me, although it does look interesting.
