A bit like in GTA3 or GT3, we could have an in-car radio so that you can choose which tracks to play. For example you use the . key to go to next track and , to go to previous track. That way players can choose what of the multitude of music we've got coming in they want to listen while driving along. And it wouldn't be too hard to incorporate the name of the song, the length, etc. into the HUD would it?
