Get yourself some sidewalk chalk from the store. Then you can use the plastic disc for the corners then draw chalk lines outlining the track. Also mark where the discs are with the chalk so if you hit a disc the track is still marked.
You can see the chalk lines of the track in the video when it is not an on board shot.
You know the guy that beat you at the last race? It was not because of his car, or motor, or battery, it is because he was a better driver. Now go practice so you can beat him.
