That is the coolest thing ever! Could you imagine the face plant if you steer it wrong. I was riding one of those hoverboards thats like a Segway scooter without the handle. It was so sketchy I kept getting thrown off of it. I used to ride a skateboard back in the day but this thing is ridiculous. This guy is obviously a professional rider. If you turn that jet too far forward, backwards or sideways you're going to get wadded up big time!!! What happens when you run out of fuel and your 100 feet in the air????
