I completely agree with you. Most cars can benefit from a properly designed lip spoiler / tail, and steps, it's all the same principle.
One thing that is based on the same idea as tail disks someone could try with a pickup is to place vertical plywood sheets every foot that would be shaped like the skeleton of a tonneau cover. At that point you might as well just cover it up, but it would be interesting to see the results.
I thought about the boat tail disk idea a while back when I was reading on the forward facing vertical splitters they put on big rig trailers, and the tailgate up for pickups, which create pockets of air the rest of the flow can slide on.
