Episode today is 'Route 666'
At about 2 minutes into the episode, when the truck has the first car going back the way it came, you can see a lighting rig of some kind behind the speeding truck. It seems like it could be a remote-controlled helicopter camera, because it's not stationary and keeps up with the truck for a few frames.
