I was interested in doing this thread myself, but I’m happy that someone’s done it for me!
Usually, the best way to predict the future is to look at what’s happened so far, and make a prediction of how this era will ultimately end. Thus far, Vettel is 25 and has competed in 94 races. Hamilton is 27 and has competed in 104 races and Alonso is 31 and has competed in 190 races; as Alonso is quite a bit older than the other two he enjoyed a great deal of success before Hamilton and Vettel were even in Formula One.
Disclaimer: I know that what’s happened in the past isn’t necessary a correct indicator, I just want to list some facts to compare these 3 top drivers.
Nonetheless, by far the most logical way to statistically compare the three men is by Vettel’s base and what he’s accomplished so far as he is the youngest and least experienced. He has entered 94 grand prix weekends so far so let’s compare than to Lewis and Fernando’s 94 first GP’s.
In terms of statistics thus-far, Vettel and Alonso are neck in neck after 94 race weekends; both had won 2 WDC’s and WCC’s at that time. However, Vettel had 5 more wins and Alonso 2 more podiums; overall Vettel is slightly ahead of Alonso, and both are ahead of Hamilton by quite a margin.
