Damage from collision seems way too high

[maddoggg]

So after watching the E3 videos for probably a 3rd time,i cant help but notice how rediculosly high the collision dmg is.
I dont mind collision dmg beeing in the game,i even like the idea,but right now it seems rediculos.
Heavily armored tanks get dmg from the slightest bumps while moving with 20km/h,jeeps explode while moving with 20km/h instantly and landing an air vehicle on low health is completely out of the question even if you land with 0,00000000000001km/h on the flattest terrain possible.

If you are going with a full speed with a buggy i can understand geting blown up if you hit a wall.
Air vehicles dieing instantly while flying with high speed and colliding with something,that's the way it should be really.

But right now the deadlies faction BY far seems to be the terrain itself.
