computers help everyone not just Rossi in F1 especially with traction control eliminating a lot of the work in corners. You can still spin them easy, but nothing like it would be without that. The hardest learning curve from other forms of racing is getting the car to move, but Rossi has a huge advantage with that with how much power a bike produces.
F1 racing has never impressed me from a racing point of view because it relies much more on technology than it does with the driver. It is definitely the sport to watch from the engineering side of things though, which is why I like to watch it.
