I mean, really, how hard is it?

Enough of a bike for safety standards and light weight, enough of a car for comfort and licensing standards. Nobody's doing it, but you want to.

1. Get a trike company (Can-Am is all I can think of) to supply a chassis. You're not competing with them, so they'll take your money.
2. Someone's got to be willing to sell engines.
3. Hack Tab A and Slot B, then all you really need to develop is the bodywork.

Now people can see an Elio in magazine reviews. It's possible to buy one. It's not $6800 and it's not 84 mpg, but the Elio MKII will be. You know, the one you develop from scratch as an already active manufacturer. And the interior is already done, with just a few sheetmetal tweaks for aero, fitting the new frame and to show it's the 2nd gen. You've got active suppliers and an active customer base. People are even willing to sell it for you now.

Of course, you'd only do that if you wanted to really make something.
