Spawned an M8 inside of the crater, CraterMA up near the top. At triple digit speed the trees do not recognize the M8 as a solid object to stop it. After launching off the top of a cliff at 90mph and hitting the ground 100ft below, the M8 began a never ending tumble which I could only stop by pulling up task manager and killing the game process. Up until I found the down slopes, every tree type of the 4 types available, would stop the M8 cold and allow it to reverse away.
