Manually Apply Cars Collision Response Force

I want to throw cars with back force after a collision like this way. Few collision examples, I have represented in the following image with its collision back direction.

Cars are moving using applied velocity and I have applied velocity continuously to move at constant speed. Just on collision, I have stopped applying velocity for some time so I can get some collision response.

I want to get collision response as per Bumper.io game: Bumper.io Part 1 (IOS/Android)

At present, I have written some code for this purpose but it's not behaving exactly like this way:

 void OnCollisionEnter(Collision other)
 {
     if (other.gameObject.CompareTag(GameConstants.TAG_ENEMY) || other.gameObject.CompareTag(GameConstants.TAG_PLAYER))
     {
         elapsedEngineStartWaiting = 0f;
         StartCoroutine(ApplyReboundForce(other));
     }
 }
 
 IEnumerator ApplyReboundForce(Collision other)
 {
     Vector3 centroid = new Vector3(0, 0, 0);
     foreach (ContactPoint contact in other.contacts)
     {
         centroid += contact.point;
     }
     centroid = centroid / other.contacts.Length;
 
     Vector3 projection = transform.position;
     projection.x = centroid.x;
     Vector3 normaliseCollisionPoint = Vector3.Normalize(projection - centroid);
     float collidedBodyMass = other.gameObject.GetComponent<Rigidbody>().mass;
 
     myRigidbody.velocity = Vector3.zero;
     myRigidbody.angularVelocity = Vector3.zero;
 
     int i = 0;
     while (i < 4)
     {
         myRigidbody.AddForce(normaliseCollisionPoint * GameConstants.CAR_COLLISION_IMPULSE * collidedBodyMass, ForceMode.Impulse);
         yield return new WaitForFixedUpdate();
         i++;
     }
 }

At present, collision response force direction does not remain as per, I mentioned in the above image. I want to force/impulse should be applied in above-mentioned directions.

Give me some suggestion so I can able to implement suggested things.
