In quite a tragically romantic yet bizarre incident, Segway boss Jimi Heselden fell to his death in the hands (or wheels) of his product. A serial entrepreneur, Jimi did not invent the Segway but bought the company from its American inventors after he made his millions selling blast barrier equipment in the middle east wars. He was taking out the company’s latest off-road product, the X2 for a spin when he accidentally reversed off a cliff.
