I hate that when you fail to move forward a square you ram things and take damage. So, I improved the vehicle motion when ramming or colliding with a wall. I also fixed some issues with trying to ram things diagonally… that was irritating. Finally you could previously take a lot of damage when ramming something inconsequential, but now you cannot take more damage than it takes to kill the opponent (and in the current configuration you only take half that damage… this will ultimately be adjustable based on your equipment).
As usual, check out the AutoFire page for the update.
