According to the YouTube video, on September 18, a BMW E30 was about to head into a corner when it sprung a coolant leak. This somehow cause the E30 to spin out and tap a wall. It seemed that the German four-door would drive away with a couple of scrapes. Well, when you leak coolant you also leak it onto the road. A Porsche Cayman GT4 was coming into the corner hot when it must've hit the coolant on the road, causing it to lose control and slam into the wall and BMW. Shortly after a VW Polo followed suit and ran into the wall as well.
Check out the video below to see the chaos for yourself.
