about passengers; what ^ said. Make a custom view, move it to the passenger side. Press tab until you're in the car of the friend you want to watch. You can also activated mouse XY panning so you can look around using the mouse.
About the more tracks part. You think going on the forum and asking for more tracks is going to get you more tracks when you haven't even payed for the game? If you want more stuff, buy the game. You're lucky to even have a demo version to play on. You should be greatful.
edit: Oh and with better graphics comes more nutheads. Just saying.
