Yes even without having the best car any year of his career arguably Alonso still could have won 5 World Drivers titles by now. 2007, 2010, 2012 for sure were opportunities (2012 might still happen but hugely unlikely now) squandered. Even though he might be the best driver today, he still hasnt lived up to this potential I dont think. When he won his first 2 World drivers titles so young he beat drivers the caliber of Raikkonnen and Schumacher (still close to his best then) when they had faster cars than him. Now he cant even beat Vettel who is not yet as good as prime Schumacher or mid 2000s Raikonnen, if Vettel has a faster car.
