Oh, so that merely gains them entry? I dread to think what trials await beyond that.... wrestling a Minotaur?
I kind of understand moral exclusion because a driver's actions might jut up against your compass, but dismissing them on a weirdly specific technicality they can't control is bizarre.
Out of interest, who passes the test into the Ring of Doom?
Well, every driver discussed in this thread won a title in the fastest car. It is not an impressive achievement, it's just the minimum display of competence. So, if that's not something special, what is?
I think my shortlist would be Schumacher, Prost, Lauda, Stewart, and Fangio. They all did something more than winning in the fastest car. Schumacher did win titles while not in the fastest car, and also showed blinding dominance when in them. He also showed how a top driver can motivate and lead the team around them to create a more successful larger entity. But he loses points for ramming title rivals and perhaps not being as good in a wheel to wheel fight as some others. Prost showed blinding speed at times, dominated in great cars, and won a WDC in a car significantly worse than the car his rivals had. He lost to a great teammate, beat a great teammate, and it took the lessons learned from that first loss to improve himself as a driver. He loses points for at times questionable motivation, and perhaps just plain slacking off at times when other drivers would have chosen to deliver psychological hammer blows to their opponents. Lauda had blinding speed, incredible technical abilities to lead development of a car, possibly upped the game in driver fitness to a point it hadn't been before, and successfully came out of retirement to beat another GOAT candidate to a title while being the slower driver in the team. Loses points for personality and perhaps raw speed. Stewart had speed, dominated rivals, won in different teams, and then quit very early. But also had the wider impact of changing the sport in terms of both driver professionalism and safety demands. Loses points for the early retirement essentially freezing his record at a much lower level than it would otherwise have been. Fangio showed up in his 40s, beat the young men with dominant driving, and completely changed how people thought of driving. But it was a much less professional era with a smaller talent pool.
Of that group, I think Lauda or Stewart might be the best GOAT candidates for their overall accomplishments, but I think Prost also deserves a hearing, certainly more than Senna does, at any rate.
