I have been trying to install add on cars for the first time. Each time, I copy and paste the data from the carcols, carvariations, and vehicles.meta and put the updated files in my game's mods folder. The issue is when I spawn in the vehicles, they are not being recognized as emergency vehicles. The lights and sirens don't activate with the [E] key; instead it sounds the normal civilian vehicle horn. Even if I go to the interaction menu, under vehicles, the option for "emergency lighting" is grayed out so I can't activate the sirens that way either. Maybe I am not copying the data correctly. I have tried with 3 different models of car and every one is the same. Any help?
