Hello!
I am very enjoyed weak vehicles - it is good that you cant drive through buildings and ram trees and etc.
And thanksfull to coders for that.
BUT! We all want realism, dont we? So why can i crash my armored car or apc by shrubs and zombies?
This is about density. If the object has much higher density than the thing it rams - it wont crash even in 100 times.
And also it would be good when i drive my vehicle into another vehicle on low speed it should PUSH it, not to RAM.
About APC - everybody knows that it can ram concrete blocks on speed without gettind damage.
