Drunk driving is such a cause for concern in Germany that a team in Frankfurt set out to create what they dub "the Piss-Screen." So how does this Piss-Screen work?
The Piss-Screen - a pressure-sensitive inlay set within urinals, enabling users to play while they pee. We installed this newfangled creation in male restrooms across Frankfurt, teaming up with a variety of bars, clubs and cafés. The game itself was displayed on a screen above each urinal, and would automatically start as soon as someone began to pee. The player could then control the car whilst relieving himself – if they wanted the car to go right, they simply peed to the right (and visa versa).
It's basically a driving game that you control with your urine stream, and if you respond too slowly and do poorly, it results in a nasty crash. In other words, it means you're too drunk to drive (and you should think long and hard about the crash you just saw). When your urination session is over, the game displays a message ("Too Pissed to Drive? Take a Taxi Instead.") with a local taxi number.
It seems like a pretty good idea... but will it work? And what about the ladies?
