Well, nearly.
This turned up on Ebay recently:
It’s a 125 mpg car that a Ford Efficiency expert made in his spare time. Looks like a cross between an Aptera and a kamikaze plane from WWII. Nice colour though.
I think several of the commenters missed various points. This isn’t about anyone designing a product for them, it’s about someone (an individual) building a product for themselves – routing around decades of industry heel-dragging in the process. We will see more of this.
