@fshow sorry but I had had to LOL at your post, because the whole point of this was that driver weapon can be reamed now, if you add this then my addition is pointless and you can just remove that instead of adding a double check what I just enabled.. :D
Check the last page here or something there is a discussion and fix, before that you could never ream in the driver seat but it seems many admins use custom vehicles wither turrets in the driver seat so I "had to" enable it.
