Hamilton is nothing like this. Montoya was short tempered, had a terrible sense of humour and had a high opinion of himself. Hamilton acheived more in 2 seasons of F1, than Montoya managed in his entire F1 career.
To mention Montoya and Hamilton is a little unfair on Hamilton.
Montoya had nothing like the cars hamilton has had though, you need to watch his early stuff at williams again and see how no one phased him. Montoya had more racecraft in his little toe than hamilton has got. He was mighty in F3000 and Cart as well and took zero prisoners.
He was an out and out wheel to wheel racer, which is why F1 bored him. Fair play to him for going to do something he would enjoy rather than sitting in a format he just didn't take personal pleasure from.
