Gran Turismo has always been about the cars. Collecting cars, upgrading cars and racing cars, but what if it was also about bikes?

Speaking to IGN, series creator Kasunori Yamauchi revealed that should fans ask for bikes, then there's a possibility of it happening.

"If that's [bikes] what users really want in the game, I think that's a possibility," said Yamauchi.

Failing the inclusion of bikes in Gran Turismo, Yamauchi said Polyphony "could consider making a Tourist Trophy 2".
