I was at a mate's place one time, who I was teaching how to drive. It had been raining heavily for a day so we went down to a local park which had a large dirt carpark to do some "circle work" (drift training).
On the way in, on the service road there was a massive pool of water across the road, about a foot deep and about 15 yards long, which we drove slowly through.
After about 20 mins of donuts and wheel spinning we left. On approach to the pool of water there was a car stopped right in the middle, to one side. he had obviously stalled driving through and was sitting there smoking a ciggie waiting for his electrics to dry out, or maybe waiting for help. With the window wound down.
My mate guns it and drives towards the water at about 50 kph. I'm like "WTF!". We hit the water and this massive bow wave comes off the car. Straight at the broken down car. The wave hits him like a frickin tidal wave. Epic.
I'm betting his ciggie went out.
