There's a lot of talk these days about the exchange of F.1 car/MotoGP bike between Valentino Rossi and Lewis Hamilton, but it's unlikely that either of them will decide to do anything more than a show.
If, then, you expect to get really excited for someone who comes from motorbikes, even if only for kinship, and landing in F.1, maybe it would be better to look at the son of the great Mick Doohan, Jack who, as you can see, runs with a helmet inspired by the super triumphant Mighty Mick!
