How the rich get concussions! Good times
The Hoverscooter; "To accelerate you lean back while gripping the handlebar" - What do you grip when you DON'T want to accelerate? It takes 20 feet to stop the thing! I suspect most people using this thing spend much of the time sitting on the pavement gripping their heads and wondering what happened. I guess if you can slap down 17 grand for this goofy thing, you can hire people to chase you with big pillows or something. (From Hammacher.com - used here for parody and education.)
