I still think they could work, but not in the usual massively/truck-sized variety on a regular car.
Something more subtle might do the trick.
Renault / Dacia had them on the rear roof line of their eco-Logan. |
Apparently they don't even work at big-truck scale. See

Wish they did. My boxy-backed Smart Fortwo should be able to do better than the measly 38-39 it gets. Well, I do break 40 when I can keep it to 65 with no stop and go traffic, but how often does that happen?
