I want to make rope as in the video. I tried to make with character joint and rigidbody but it was way more heavy for mobile.

You can put an object behind the car and make the illusion of pulling using smooth move, you can use Smoothdamp to follow the rope point in the sphere:

public Transform Target;

public float SpeedT = 2f;
Vector3 VelMo = Vector3.zero;

void Update ()
{
transform.position = Vector3.SmoothDamp(transform.position, Target.position, ref VelMo, SpeedT);
}
