[Unity 2021]Car Race Game-Day 2

The game is a car race game on terrain.

Here are the current problems:

• Car 'clips' into the terrain
• Car can move  forward,roate,but the movement does not follow the rotation although I used Vector3.forward
• OnTriggerEnter of the start and finish line s not working.The functions cannot be called because the collision cannot be detected.

Please use unity 2021.3.27f1 to open this project.
