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.
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.

So just aim your rearview at them.

Be better than your enemies. Annoy them and don’t cause an accident in following Hammurabi.
