Trivia: The company that offers work to Lightning McQueen is called Dinoco. Dinoco is the name of the gas station that Andy stops at on his way to Pizza Planet in Toy Story.
Other mistake: The monitor from inside Mack's trailer displays his whole face while talking to McQueen. There is no camera outside of Mack that can display him in that fashion.
Suggested correction: The camera in the trailer may be a TV video instead of a camera.
No, McQueen is talking live with Mack through this monitor.
Continuity mistake: Before Lightning falls off the end of Mack's trailer, you can see Snot Rod and one of the other cars running alongside the trailer. But when the camera moves to show Lightning coming off the trailer, you can see alongside the trailer in the background, and the cars are now missing. Camera switches back to the front of Mack, and the cars are back alongside again.
Suggested correction: Actually, they are still there. They're just out of view.
Trivia: The canyon around Radiator Springs looks like old car bonnets and ornaments.
Other mistake: At the start of the film when the commentators are explaining the tie situation between the 3 cars the green arrow to the car is out of alignment and misses the car, instead pointing at the track.
Suggested correction: Pixar Creative Director, Jay Ward, who is this film's team manager (as well as art coordinator) has stated that this was deliberately done as a joke, for fun. Chick Hicks' green arrow does not line up with Chick Hicks. That it's a little bit off, in the same way that Chick Hicks is a little bit off. This is the video with Jay Ward explaining: https://youtu.be/ZkJre-eC-zE?t=25.
