      Your rearview mirror can do that. Yes. A larger concave mirror can direct more light back, but then you have to have a 3 foot wide mirror taking up space in the cabin or exposed to the weather outside the car, it would be prone to failure.

      So just aim your rearview at them.

        I was thinking a mirrored surface on the motorized pad near the trunk of vehicle on outside. rear view doesn’t seem to have enough ooomph behind it to be satisfying.
