Going back a couple of posts, I don't see a reason why there couldn't be a cert specifically for "hacking & jacking" so that you can take over an abandoned/parked enemy vehicle. People shouldn't leave stuff lying around if they don't want it to be used!

Armament wise, if you have the jacking cert, you should be able to use whatever is installed on there by the previous owner, but not remove them or pull any new modules for it. Once the vehicle is destroyed, the modules are destroyed, and you have to go steal another.

Now maybe if you hack a vehicle and can also hack an enemy terminal to get a hold of their upgrades, that would be audacious since its probably defended and people won't take kindly to it - in which case perhaps make all sidegrades available to be unlocked by all players, but where you use resources to unlock your own, you use certs to unlock the opposition ones for use only on their vehicles.

That gives you specialization in taking and using enemy tech.
