Interesting analysis, but the main point remains: You can not compare drivers across different eras. Is Lewis the GOAT? Yes. Is Michael the GOAT? Yes.
The best drivers make it to the top, but that's it. Alonso only won 2 and he was just as good as Lewis and Schumacher (arguably better considering what he could do in cars of almost any quality, lewis had a bad car once his entire career)
But yeh these GOAT conversations better with beers and stakes and people yelling at each other in person!
but agreed, this is true in any sport, there's no real way to compare across eras and in the end it's just opinion.
I agree, cross-generation driver comparisons are really hard.
