I mean, c'mon. It's not that hard to work out. Wheels move, people sat on carts and stuff with wheels on them. Why didn't someone think "I could sit on these wheels and power it myself instead of a horse".?

Totally mental. Also consider that (apart form some unverified sketches) the bike first appeared around 1820-1830 as did the first cars. In fact the car was first conceptualised BEFORE then.

Literally, it's like a weird collective consciousness. If it hasn't been invented, most people just can't imagine it. But once it has, everyone can imagine it.

Like until the 14th century, NO ONE had ever used perspective in art. So tens of thousands of years of evidence of human drawing and no-one can even comprehend perspective, then suddenly, everyone does it and it becomes the norm.

Dunno where I'm going with this. Probably to zero replies, but fucking mental huh?
