I thought for a second you were gauging interest in making aero aftermarket wheels. I want to say yes, but the answer is really no to that because those solely chasing fuel economy really don’t care much about what it looks like. I mean, they’d get a boner over fender skirts. I prefer to see what’s under the skirt. There might actually be a market for this though.
Anyway, your real question. Think outside the box, people. If you are selling, market it to non-Tesla people. These would look great (without hubcaps) on a lot of Honda/Acura. Having aero hubcaps is the extra but not the main thing.
