As time goes on (and thanks to the power of the internet) I find more and more examples of vehicle designs/features I originally thought were original or unique that in truth are derivatives or copies of something that came before. Not that the derivatives aren't still cool as all heck. This is especially true as an American who is still learning about obscure Microcars and Cyclecars, especially foreign. I've been binging on Scharroo's Grab Bag on Flicker lately, and Bing image searches for micro- and cycle-cars... WOW, what goldmines of obscure treasures!
