``It`s an entirely different world...``
Valentino Rossi says he still has not decided if he wants to switch from MotoGP to formula one.
The multiple world champion on two wheels told German magazine Motorsport Aktuell that, following his serious group test in a Ferrari and subsequent return to a MotoGP session, he still has `more fun` on a motorbike.
"It is also a completely different feeling in a F1 car," the 27-year-old Italian, under contract until the end of the year, said.

"I am in two minds -- I do not know at the moment what I am going to do."

Rossi said he wanted to test at Valencia in order to gauge his speed alongside F1`s established runners. `Vale` logged decent lap times, but his car`s V10 engine and 2004 bodywork meant that any real comparison is difficult.

Meanwhile, he refused to compare his MotoGP bike with a grand prix car.

"It`s like a football player changing to basketball," Rossi acknowledged. Everything is different -- it`s an entirely different world."
