Limit FOV while in a vehicle to reduce the abuse of "fog wall"

[GarlicAAZ]

The fog wall issue, i think, needs no explanation. But i do want to point out few important things about it - while it is impossible to "fully" fix the issue, it is possible to significantly reduce effect of it, to make it much less effective.

fog wall can be abused anywhere, but it has the worst impact when in a tank. If you are infantry, you can only use it to spot someone, but in a tank you can use it to aim and shoot at the enemy with your cannon, while enemy has no chance of seeing you.

if FOV was additionally limited for players inside vehicles, that would significantly cut down the extra view distance that can be gained by looking at the corner of the screen. Currently players can choose FOV settings somewhere between 80 and 115, which is a big difference. Higher FOV mostly only provides benefit for infantry gameplay, to be better aware of things in close combat, while for vehicle users this is much less beneficial (if we exclude the fog issue itself); so limiting FOV on vehicles should be relatively harmless to the gameplay.
