I would guess that with any type of HGV the fatalities are caused not by the impact (most occur at junctions where they're only moving slowly) but from being crushed under the wheels.
One of the worst things about many crashes is the turning speed that can be achieved. Even if the driver of a large goods vehicle could get feedback, it would probably all happen too quickly in many cases.
