Wednesday 21 May at 18:31 : Flamboyant MotoGP champion Valentino Rossi has admitted he would like to know how he would have fared had he decided to switch to formula one with Ferrari a few years ago.

The Italian tested for the famous Maranello marque several times, and seriously considered switching codes, but ultimately decided to stay on two wheels.

"'Sorry' is not the right word," Rossi, now 29, is quoted as saying by the publication Affari Italiani on Wednesday, "but I do have some regrets because I am still curious to know what I could have done."

Rossi, who at the Le Mans circuit last Sunday equalled motorcycle great Angel Nieto's tally of 90 victories, explained that he simply baulked at moving to F1.

"I was doing well in the testing -- it had always been my dream to race with Ferrari.

"But at that time I was not ready for the jump and I was in the middle of the motorcycles.

"Driving F1 cars is extremely satisfying," he added. "It is less a vehicle and more like an aeroplane, giving you great sensations.

"But for a motorcyclist it is also a strange feeling; putting your legs into a black hole."

Rossi refuses to rule out switching to four wheels at some time in the future.

"I want to do some more racing (in MotoGP) and then I want to spend some seasons with my passion; the cars. Perhaps rallying, maybe something else," he said.
