the pee efficiency vehicle
It's not fair that men always get to have more fun with their pee. Um, just saying, most of the cool interactive bathroom installations we've seen are urinal based, like this really creative campaign by Leo Burnett Tailor Made in Brazil for the new Fiat Uno.
To dramatize the Fiat Uno's fuel economy, they installed an interactive, gamified ad above urinals in restaurants/bars. When dudes peed in the urinal, the Fiat Uno on the screen above would travel a certain distance down the road, powered by a sensor that translated milliliters of pee into kilometers based on the Uno's actual fuel economy. The distance traveled based on each mans' pee was showcased on a leaderboard for fun.
Now if cars were only really pee-powered.
