Aptera is getting pretty close to shipping first customer cars this year, or at least seems to be, while this is a one-off research prototype - I think your comment is not quite fair.
I'm pretty sure they could bring this to market almost immediately, if there was a sizeable market for this kind of vehicle.
Aptera on the other hand has been around for a long time now, changing their product strategy every now and then, making announcements... I wish them all the best, I really do, but until they actually ship something, I will also stay skeptical.
