(I'm sure most vehicles experience problems as well)
HAV-
So today my gunnlogi was destroyed by something that can KO it... A freaken staircase.
For tanks, turrets are the major flaw of tank physics. It's cool that CCP added physics to the turrets(something most games don't bother with.) but the way the turrets interact with other objects makes no sense. If you touch an object that isn't programmed to be affected by external force, all that force goes to the tank. Which is how it works IRL, but not so violently. A tank can be flipped over by anything its turret touches. The damage they take is especially dangerous to shield tanks.
LAV-
This has somewhat to do with HAVs.
If a LAV so much as taps a HAV... They're dead. All though you probably like this if you hate LAVs but it needs to be changed.
With walls and non interactive objects, LAVs hardly take any damage. If these structure can't be destroyed then their hp would be pretty huge. Why can a HAV can blow them up but a wall can't? Also it knocks a good chunk off HAV hp.
DS- Sort of the opposite of LAVs. If they touch a wall there is a strong chance of doom.


CCP-
Please fix the physics with vehicles, and integrate the infantry moving to the side when being rammed by low-med speed objects.

I hit a wall in my Limbus at full speed, and took a 1/5 of my shield HP. SO yea, it's nothing to worry about.
