There are a lot of problems with this map
1. In the first surf scenario, turns cause unexplained sudden deceleration
2. In the second surf scenario, it is extremely difficult for humans to obtain initial acceleration if the scenario is randomly crossed through a wooden frame
3. In the fourth surf scenario, turns are extremely prone to inexplicable sudden deceleration
4. In the last gliding scene, even if it is a straight slope, it will suddenly slow down inexplicably, and it is extremely easy to suddenly slow down inexplicably at the corner
