It would be cool if you could duck while sitting in the car in order to reduce chance of being headshot-ed.

For example : just hold the crouch key and your character ducks forward. Nothing fancy but goes a long way.

Heroes & Generals game had this and it was great. A very simple animation which greatly increases your survivability since you're already immobilized in the car and you can't shoot from it.

It would be fantastic if everyone in the car could do this just like in H&G.

Cheers !
