I've moved this from where I originally posted it earlier today.
Here's one I found on another site(4-Free) and checked back to source,I am downloading now to check it out 'Ferrari Virtual Race',download and more info available at
http://www.ferrari.com/English/Community/Ferrari_Virtual_Race/Pages/Game_home.aspx
Quick update,15 minutes and 6 laps later,seems quite enjoyable.Won 2 races and had a fine smash at 170mph.
Easy to set up and can be controlled by various devices(I'm using a flightstick).
Not bad for a free racing game.
