[HELP] Stop Replaced Vehicles Being Driven by NPC

Hello, first I want to say thank you to everyone for the amazing releases and the help and effort that goes with them, you guys are T1!

I tried a million and one different ways to get OpenIV to install on my computer, I kept getting a direct X error, so I unfortunately settled for replacing custom vehicles.

My problem is, now I see NPC driving the replaced vehicles (obviously because the custom vehicle uses the in game vehicle name.) Is there a way I can disable the ability for the NPC to do this? The replaced vehicles are supposed to be “special/unique” and they are not if the NPC is using them.

Thank you for the help!
Buck
