Please add the ability to "set", via Campaign Manager Arena Setup, the time it takes for a destroyed vehicle to be removed from the battlefield.
I realize that this probably required a change in the way that destroyed vehicles are shown, maybe the original "blowed up real good and gone" graphic can be part of a randomized setting with "burning real good", "turret blown clear off", and possibly other mutilations such as currently occur on the new plane graphics. The randomization would allow a variety of wrecks, ensure that not every vehicle destroyed is a wreck and this is all controlled by the system makes when a vehicle is destroyed.
Obviously this would be have to be on a "timer" as it would tend to wear down the frame rates over time with a large buildup of destroyed vehicles.
