Vehicles and Mounting and Turrets oh my

(moved from public forum)
While looking through the vehicle mounting code I noticed a few things.
- It supports multi-seater vehicles
- It allows one of the players to mount a turret on that vehicle.
- It allows one of the players to be assigned pilot.

Are these cool features or what???? It's Halo functionality out of the box!

My question is, is there a mod out there that actually utilised all of these?
For example ( coming up with ideas off the top of my head ) codes to make a...
- jeep with a m60 on the back
- or a Zarg EVA with a Rail augmented Plasma Cannon bolted on the back
- or an elephant with a 3-saddle seat and bazooka thrown in for good measure.

Can anyone let me see an implementation of something like this if someone doesn't mind sharing their code please :)
