I think it would be really useful to have a keybind/quickbar button to turn the mod on and off, if for whatever reason you want to just place down a car. It would also be cool to add support for more vehicles, specifically the tank and maybe modded vehicles like AAI. I'm asking because I'd like to try AAI programmable vehicles, but it seems like it will be troublesome with that and Instant Car together, and I can't play without Instant Car anymore.
