We are about to see unbelievable Porsche crash recorded at the International Arosa ClassicCar hill climb event in Switzerland. The race track is a 4.8 miles hill road stretching from Langwies to Arosa, including 76 turns and an altitude difference of 422 metres. The Porsche driver lost control of his car on a sharp turn and went straight into the protective fence. The driver was not injured, but five spectators that were near the fence at that moment were slightly injured. These are unpleasant scenes, but they are inevitable part of the motorsport. Watch the video below if you are curious to see what exactly happened.
