Very late response as I'm just curiously looking through some of the packs:

The Mechanoid patch is viable now for that I guess but honestly making VAC more compatible with Vehicle Framework is not a bad idea... we did implement a Radio Filter after all...

There are no immediate plans for VAC atm but that might be something to add to the list of a potential update. But honestly people figuring out how to create patches for VAC is always a welcome addition

I would love to add vehicle voice lines, sadly there's no way to do that for now. I was thinking of adding them to mechanoids, but I'm trying to see if it's possible to integrate it with vehicle framework.

Somone should make vehicle operation specific voice lines. "Bugger the clutch, go!"
