Why OnCollisionEnter() Called multiple times without touching.

When it goes away from collider after colliding,

OnCollisionEnter() and OnCollisionExit() are called Dozens of times.

In the Images, white lines shows contact normals from contact points.

While the white lines appears, OnCollisionEnter() and …Exit() are being called.

It is called until the distance (between colliders) reaches 0.8.

On the earth, what is that?! why is that?!

Please help me!!!

A code sample of your script would help a lot.

Does your script look for the tag of the collider ?
Is there only one collider on the car ?
