Hint: Avoid getting lost:
If you ever get lost in the desert, follow Mater or any other car without bumping into them. They will take you back to Radiator Springs.

Hint: Lightning bolt:
The first stripe (near the fire house) of the new road is actually a lightning bolt.

Glitch: Mac goes through house:
Go to Flo's Cafe (the gas station) and look for Mac (Lightning's semi). Push him at the side tire until he starts to move. After he moves, keep pushing him until you hyave pushed him all the way across the street to Radiator Spring's Curios (the old store). Then, push him most of the way through the house. Go to the back and you will see his head on the other side. You can sometimes see him through the window on the side.
