Run Over [three-actions]

You try to run over creatures or ram another vehicle with your vehicle. If you maintain control of your vehicle, it moves up to twice its Speed in a straight line at the vehicle's current heading. You attempt to run over any creatures in your path two sizes smaller than the vehicle or smaller, and you can attempt to ram one target creature or object in your path one size smaller than the vehicle or larger.
Each creature in your path, including a rammed target, takes the vehicle's collision damage (basic Reflex save at vehicle's collision DC). If the rammed target is a vehicle, its pilot can attempt a piloting check in place of this Reflex save, with the same results. If the target of your ram takes damage, you and your vehicle each take collision damage (no save) and your movement ends.
