View angles from vehicles vary very much, which is not realistic.
For example commander of speedboat can't look back, the view angle is very limited. All vehicles should allow same possible view angle behind as infantry soldier has, especially when there's no seat behind the player.
One's neck doesn't just suddenly become stiffer after entering a vehicle :)
Place yourself for example as speedboat commander in the editor. Notice that your view angle behind is very limited. Looking behind you should see the rear gunner and passengers sitting in the back which is currently impossible.
I think is very important issue in gameplay and immersion terms.
