Stop a vehicle from acting as traffic

I want to transport cars while traffic is on. But obviously if I spawn a car on top of my flatbed and spawn traffic, it will too act as a traffic vehicle. Any solution?

 

Spawn and start traffic before spawning a vehicle to transport. That's the way I have been doing it.

 

Ok thanks

 

Yeah, it would be. Anyway, thanks.

 

I have found a way where you can do realistic police chases with traffic. Spawn the car you want to chase and put it in flee. Then spawn traffic.

 

Yeah, there are still a lot of problems with it. It still would be nice if an app was created.

 

I don't see it this way. it's quite the opposite, the flee mode ai slows down to make turns, avoids other cars well enough, and rarely crashes. the chasing ai, though? overshooting turns, crashing into other vehicles, and wrecks its car within a few minutes. chase AI seemed to have gotten overly dumb with the latest updates.
Also, if the fleeing car gets stuck, use free camera, hover the camera over the open path, then spawn the car at the camera. there's a special binding you have to map for the one without resetting the car. no need to drive manually.

answering OP's question,

1. go to UI apps
2. add the AI manager app
3. switch to the traffic car you want to disable(remember to tick the associated option in the options menu)
4. select AI mode
5. set to disabled

easy as that.
