After playing around with the settings more i found this issue is even more nonsensical then id originally thought:
If you play in third person you are still able to enter vehicle zoom.
Well it turns out this version of vehicle zoom inherits the aim sensitivity from the third person camera not first, so if you have your vehicle aim sensitivity set to maximum you are able to 360 the turret around nearly instantaneously, no aim delay or max turn speed cap whatsoever.
DICE, Battlefield Studios, whomever is incharge of this game, you have got to fix this issue as this is just ridiculous.
