For rig shots, the car should not even be on let alone driving 50+mph on the freeway. If your recording video, thats a whole other subject. But as far rig shots go, the engine should not be on because the vibration will cause the rig/camera to shake. Also, the car should probably be moving less then 5mph. Anymore is just overkill imo.
