Some vehicles can see only on 1 side, some have full vision.
Vision range is not affected by guns range of the vehicle. I like both fog and vehicles a lot so patch would be awesome.

Even more awesome would be if full vision around the vehicle was available only for light cars/vehicles. Heavy vehicles like tanks or APCs would see only in front similar to the bugged side-view some vehicles currently have. If vehicle turret is active it would have full gun range vsion like you get from long-range pawn weapons.
With all that potentionally leading to vehicle commander seats for situational awareness.
(is it possible?)
