Place a tracked vehicle on the road on Chernarus at 044114 and tell your driver to go to the airfield south of this area. At the sharp turn at 045119, the vehicle will attempt to turn without breaking, and usually flip itself over or rollover down the hill. (Other locations on various other maps, or even just in fields with a slight downwards slope will also cause this if the driver is going fast enough and decides to pull a sharp turn.)
