Hm. Except for that Honda concept, I could see most of ^^ that above being concept art for a game like the Fallout series, that has that retro '50s sci-fi theme.
Not quite sure what I think of that Honda concept. With that low front splitter, it's obviously meant to be a track car; it'd get decimated nearly instantly offroad, or even general city driving. The design looks like it'd have a lot of blind spots, though I imagine they'd sort that with strategically placed closed-circuit cameras and monitors in the cockpit. Looks like it'd be a mid engine, rear wheel drive layout.
I think the low profile tires throw me the most. I don't think there'd be enough meat on 'em to "deform" and provide grip in high-speed cornering. Look at the meats on F1 cars; huge, by comparison. I can only guess that this is supposed to be a racing concept, what with the single seat and the racing harness. Probably an art school student's concept, if I had to wager a guess.
