it's much much harder to race Moto GP and win than go fast in a car, and much more dangerous. If he wins on 4 wheels it'll just be icing on the cake of the greatest GP'r in history. Agostino wasn't going near as fast when he won.
It can't be easy to drive one of those things though, even with the controls they have. Its the pinnacle of the sport, and I am having a hard time believing that just because he can ride a bike he can drive a car, especially one that extreme, and drive it better than the other guys who have been honing their car specific skills for most of their life.
Two offs in two days right? He better be the worlds fastest learner -
I don't agree that moto GP is more dangerous... I do agree that it is more difficult.
It is more difficult because it is multi-dimensional, power to weight ratios are similar, with signifiganly less traction available, and the rider is a major part of the vehicle behavior. There is worlds of difference between the two sports.
This discussion has been made at MO before, but here goes:
The cars corner and brake a lot harder than the bikes, there is less speed differential between their high and low speeds. The biggest difference for the bike pilot... he can't use his body anymore to affect the vehicle dynamics.
Eddie Lawson talked a lot about that when he went from GP bikes to Indy cars.
More recently Biaggi talked about the same issue in his F1 test.
The car driver today has to be very technical to communicate with the engineers and data management people. It generally takes years to become adept at this, just as it takes years to hone a fast bike style.
Rossi has shown himself to be a very good development rider, he may very well be a fast learner with good interpretive skill.
Whenever Rossi stepped up to a different class (125 to 250, 250 to 500 etc) he crashed a lot in his first season. Top racers have to perform right on the ragged edge, and how can you learn where that is without going too far occasionally?
Rossi grew up racing karts and then moved to bikes, so he already knows the basics. He excels in machine control, set-up and optimising, and (mostly) has a cool head. It seems to me that he has all the right ingredients to be very successful at F1.
F1 cars are not easy beasts - they brake and corner at 4G+ and drivers have to be amazingly fit to race one for 2+ hours. In addition the cars are very technical and termperamental beasts with even minor suspension and aerodynamic changes given them a jekyll and Hyde nature. It takes long time to understand how to make an F1 car go fast. While nobody disputes the skill needed to win Moto GP I'm not at all sure it carries over to F1.
