Radiator Springs Circuit:

1. Jump the fence at the break and drive past end of fence
2. Turn offtrack, hit other side of sponsorship wall attached to red building, then turn onto Main Street Filmore's Nature Preserve
3. On the second-to-last turn, go through the barrels and try to go between the wall and the tree
4. On the last turn, just cut through the barrels North Willy's Butte
5. After you finish the area in the canyon, find the next area of barrels and go straight (theoretically could work well with all abilities)
6. Similar to RSC, either jump the fence (theoretically better here) or drive past end and jump at most optimal time over the fence
