How to make a race track ?

Cool demo...

The demo was made some months ago by the creator of S3D Library (a.k.a Marcus   )
 
I have almost forgotten the S3D library.... but it is really interesting to learn.

Regarding the car racing, I have still some questions :
1. how to make a race track ( a little map on the right upper corner) to track the player
2. there should be some opponents, how to add those opponents' car to the game, and they should appear on the little map on the right upper corner too.
3. to make a start and a finish line

Still scratching my head on how to make them ...
