some data loggers that people use on tracks have a G-ball that shows the acceleration and cornering forces of the car. I think this addition in the game will greatly increase the fun and can aid in the improvement of your driving (to not exceed the traction circle). you can easily compare the handling and acceleration of different cars and it'll just be pretty cool. plus you can really see when the tires are wearing out and it can help you tune your car's handling by taking it to the skidpad. I'm sure it's not too hard to add this into the game. most of all, it can help you with the smoothness of your driving...
