You are correct.
I find the easiest way to visualize this is to consider the case of a brick wall and two equal golf carts collide with the wall on opposite sides at 20 MPH. Then consider what happens if the brick wall is removed. Each cart will realize the same deceleration regardless of whether the wall is there or not.
