Throw car out of the circuit, based on its facing direction using physics

I was working on Car Wars game so I require throwing the car which crosses circuit boundary.

The following image depicts my point clearly:

Now as per my programming setup, I require throwing my car through force/velocity manually applied and I want to flip the car in the car throwing direction.

I have tried myself about this but didn’t able to get the desired result.

 myRigidbody.AddForce(transform.forward * 80f);

            Vector3 currentRotation = transform.eulerAngles.normalized;
            myRigidbody.angularVelocity = new Vector3(currentRotation.x * Random.Range(10f, 40f), Random.Range(10f, 20f), currentRotation.z * Random.Range(10f, 20f));

Here are the car inspector settings:

Now share your side suggestion regarding this, I want to give force and angular velocity manually based on side of the circuit car diving.

It looks like you need to rotate your car around an axis perpendicular to the car’s driving direction.
