Would an Arcimoto FUV work for you? Those are available now. (They don't have solar panels and probably have much worse aerodynamics than Aptera. On the other hand, I think Arcimoto has the right idea with front/rear seating rather than side-by-side.)
I think they have half-doors now. It's kind of a weird thing not to have fully figured out at this point, but I give them credit for actually releasing a product and iterating.
