Other mistake: In the opening scene where the two cars race. they use a traffic signal to start the race. This traffic signal is in the middle of nowhere and there is no intersection at this light and a single lane road. Also, there aren't even supports for the traffic light on either side (which would be necessary because the light is suspended from a wire), which is most visible during the crane shots.
Other mistake: During the scenes when Ford and co are inside the race car trailer, there are amber lights flashing over them as if they are driving under streetlights. However, the trailer they are in does not have windows or sunroofs, as seen in all the exterior shots, so there is no way passing under streetlights would be visible inside.
