LumenRT U10 - Attach Camera to Car

Hello,

I'm trying to attach a camera to a car. I create the path, put the camera inside the car, create the clip - fine so far.
As soon as I select SETUP the cars start moving along the path again and the car into which I have carefully placed my camera drives away before I can select\link it.. : )
How do I stop the traffic animation? Tried turning off play animation, but that doesn't seem to apply to traffic.

Thanks,

Tom F.
