so he isn't.
I mean...many drivers can win championships in a good car, heck even eddie irvine came close to Hakinnen, to be a legend you need to be much more then that.
Fangio was a legend because he dominated, and he never make mistakes, in a time where the slightess error could kill you.
Senna was a legend because before he won champsionships, he already shine in much lesser cars like ] Toleman and lotus, he has also taken a step forward in defining what is a professional racing driver.
Schumacher was a legend because he is immersely talented, and he is the first who exhibits an allround leadership quality to create a winning package.
so far hamilton has only proven that he 1. he has a lot of raw speed. 2. he is good in rain.
hardly enough for legend status, case by case Alonso is much closer to being a legend that Lewis at this point. If hamilton in the future would have the chance of driving for a lesser team, have a tough season then win by sheer brilliance against the best drivers in their top form, then it would be appropriate to start comparing him with other legends.
