There was a lot of innovation crushing people until it got banned. (Or sometimes banned before it could crush).

Ground skirts, banned, and then Lotus 88 immediately after that also banned. McLaren's multiple brake pedals got banned after like one race?

Pretty sure if you go back to the 70s and earlier there's a long list of banned tech.

Six wheelers were cool. I kind of miss the times when they had way more technical freedom.
