A London motorcyclist got tired of smelling bus exhaust and pulled an aggressive overtake on a blind bend. Surprise! A shiny silver Porsche Macan was waiting right around the corner. The head-on smash didn't hurt the drivers, but it completely vaporized the motorcycle's fuel tank. It sprayed free, premium gasoline all over the luxury SUV's hood and windshield. If you want to wash a Porsche with petrol, there are cheaper ways to do it.
