Yeah fonts thats one for the more sophisticated fellows
The controller stuff is actually a nice idea I dont have a controller though and I dont see a clear way to send forcefeedback (maybe its handled in the backend) (and thinking about it I dont know from the top of my head how to determine if the car is flying or not (if it has contact with the ground))
The continuous night racing can be done why not (just ask the player "one more race?" and bring the opponent dialog up if the player decides to race the car will be teleported to the start by the current code too (if not then just continue from the finish).
