GameObject gets stuck in the track's Mesh Collider when the GameObject is moving on top of it
How to reproduce:
1. Open the user's attached "cosmic_project.zip" project
2. Open the "TestScene1" Scene
3. Enter Play Mode
4. Hold the "W" key to move the GameObject
5. Observe the Game view
Expected result: The GameObject moves smoothly without getting stuck in the track's Mesh Collider
Actual result: The GameObject gets stuck in the track's Mesh Collider
Reproducible with: 2018.4.28f1, 2019.4.12f1, 2020.1.9f1, 2020.2.0b7

Resolution Note:
The main issue in this case is the fact that the mesh that's being used here contains a lot of triangles that are inside the mesh's volume. They are touching the mesh surface and are therefore involved in collisions that produce impulses. Removing those extra triangles produces a much smoother ride and prevents the vehicle from digging into the ground randomly.
