Somebody should do that as a kit-car rebody. It has the wheel/body proportion kids these days go for. And wheelwell flares.
Edit: I've been looking again at Ross Lovergrove:
In this Youtube video [yootoob/watch?v=e8vZBXdOeq0] (complete with irritating background noise) he discusses how he discovered the Morelli banana car (he credits Pinin-Farina in 1974), and did a 50/50 morph of that shape with a water droplet. The video implies that it works as both a forward and reverse tricycle.
