There's no such thing as the greatest F1 driver ever, it's simply not measureable. Not even by stats as you can pick them apart forever and a day taking into account the relative competition, number 1 status, teammates, regulations, tyres, being in the right car at the right time etc. Far too many variables. It's just a subjective opinion we have to serve some kind of weird satisfaction in declaring our favourite great as the all time greatest.
There are only stand out drivers through each era that rise to the top, regardless of whether they won 7 championships or none at all. Fangio, Clark, Villeneuve, Senna, Schumacher, Hamilton (as well as a few others no doubt) are all some of the all time greatest racing drivers in their respective eras. Trying to compare drivers that raced 10, 20, 30 years or more apart though, seems completely pointless.
Looking at the records and the numbers is midly interesting but they don't really tell the whole story of any drivers career, for better or worse. But growing up as a kid through the Schumacher years and watching him reach the numbers of Senna before promptly distancing himself to the rest in wins, poles, laps lead etc.....that was something truly special, even if I was never a big fan of his until his final few seasons and I found myself rooting for him against a young Alonso. But his numbers never really made me think he was the best ever, just that he'd been the absolute best in his era by a country mile and I find it the same case today with Hamilton.
The fact he's caught up with Michael's numbers and begun to surpass them is every bit as special as when Michael was doing his thing. Of course Hamilton's hybrid era years with Mercedes have given him dominant cars to catch and pass Michael's numbers but he had seven seasons before that where he didn't once have what can be described as a dominant car and managed to win 21 races, during a time when Red Bull had a truly dominant car for a number of seasons. Yes he had championship winning cars in 2007 and 2008 but Ferrari was a good enough match over a season for them not to be dominant cars. What he was doing at McLaren during Seb's time I feel gets massively overlooked these days since he's been winning at Mercedes for so long. Although he had an up and down time at McLaren I think he produced many of his best drives when up against a dominant Red Bull and Seb, when not many other drivers other than Alonso were able to get anywhere near Newey's masterpieces.
Ultimately nobody gets to 90 plus race wins and poles without having dominant cars during their career. But the greats always get a dominant car due to their performances when they weren't in the best machinery. Save the greatest of all time nonsense but absolutely well done to Lewis for his records so far. Staggering that anyone could better Michael's numbers and it's been a pleasure to witness. I'll be making the most of it until he calls time on his racing days.
