Backseat gaming enhanced with GPS

Most families these days often install some form of entertainment system in their vehicle, with a CD player being the bare minimum unless you are traveling with a bunch of karaoke lovers who adore practicing their numbers acapella-style. Gaming console installation in cars and SUVs are gaining popularity as it keeps the kids quiet in the backseat during a long road trip, but how about offering something a little different this time? Turn your everyday driving experience into something more interesting by incorporating the Backseat Playground, a GPS-based game that is currently undergoing tests in Stockholm across a 45 square kilometer area. Will the final product be a killer application or yet another flash in the pan?
