Welcome to this short but confusing Hell Park.
In this Hell Park, you discover a Down Hole. This means you need to go down, not back.
The title of the map is supposed to help you not getting lost, but it seems to confuse players more than it helps them.
Also, the fact that you're going fast doesn't excuse you when you crash into a wall.
When in doubt, turn left.
Also, I know that the GPS isn't helpful, and you should know it too if you watched the GPS, but as we all know, nobody watch the GPS, so this should not be a problem.
