I've always loved the insanity of 40's~60's era concept cars.
"What's that? 4 wheels are good? Well that must mean that 6 would be even better!"
"Nuclear energy!? We'll stick a buncha that into a car!"
"Wouldn't it be great if your car could detect a collision before it happened? Well, we're gonna stick radar (in the late 50's) on our car so it warns you before you hit something."
