At what angle the fragment of a map is placed. This doesn't seem that important for decorative elements in background like trees, they never rotate, but chunks of map do. I don't know if you can even leave track in that game, so I don't know if you can collide with a tree.

It is also possible that the racing track is stored like a bunch of vectors, array of vectors, "this goes stright and up" "this goes a bit left", "this goes left a lot".

Knowing how it was made back then wouldn't help you much with making games now, technologies are very different.
