https://elonmusk.today/ has a looootttt of exaggerations that ended up being completely incorrect. It also has plenty of outright lies.
Just from scrolling a bit you can find plenty of indisputable lies:
Lie: https://twitter.com/elonmusk/status/1374619379929772034 Lie: https://twitter.com/elonmusk/status/1256239554148724737 Lie: https://twitter.com/elonmusk/status/1078010341651492865
Just to link to a few.
Scrolling through the list, though, you can't help but know that Elon knows at least some of his exaggerations are bullshit, which would turn them into a lie. For example: https://twitter.com/brenttoderian/status/1557224539267817472 turns what seemed to be an exaggeration of a product being ready into a straight up lie.
Does knowingly miscategorizing facts count as a lie? Because I'm not convinced Elon is stupid enough to know that Twitter was not lying about bot numbers.
If $80m turns out to be $10m, is that a lie or an exaggeration?
