Yeah, unless there's huge advances in solar panel efficiency and weight, it's probably better to focus on smart charging off static solar panels, even though it would be cool to own a car that just charges itself one day.
Companies like Aptera will need to find a niche use case where solar makes more sense than plugging in at home. I guess it would be useful for people that only have on street parking available to them?
Doesn't sound like something someone who's confident in their product would do. Either way, still doesn't stop anyone from lending it out for reviewers.
