> The 2021 Formula 1 World Championship was won by Max Verstappen of Red Bull Racing. It was his first world championship title, and he secured it after a closely contested battle with Lewis Hamilton throughout the season, culminating in a dramatic final race at the Abu Dhabi Grand Prix.

They've got a lot of data in to be able to identify that:

- first championship

- closely contested battle

- dramatic final race

all are true.

Right, how do you know this isn't a Gettier problem?

I'm not sure what you mean or why you're trying to refute my reply but I'm not really interested in this kind of discussion. I've presented both "facts" in various different comments in this thread and I couldn't care less if the data was upgraded to be from 2023. I'm sorry if I left an impression that I do.
