William Towns was the designer responsible for, among other things, the Aston Martin Lagonda. A car so futuristic, that quite a bit of the amazing technology didn't work when new, and still terrifies car restorers today.
He was very much ahead of his time. The video shows The Hustler, complete with removable fibreglass body panels so you can "repaint" your car by changing them over. Just like a Smart car today.
There's also MicroDot - a hybrid powered by batteries but including a tiny engine to charge these up. BMW made some swoopy sports car a few years ago that worked like this, but the MicroDot featured working indicators too.
