Reverse Tracks

[rookie1]

The lap counter increases when the car pass through timing sector 0. In the track reverse code, the timing sectors are also reversed. So the last timing sector in the original track becomes the new sector 0. This causes the lap counter to increase at the wrong place.

Car position depends on the relative distance from the starting line (timing sector 0) to the current patch. These are calculated during track loading, in BEZIER::Attach() and TRACK::Load(). I guess when the track is reversed, the relative distance is not recalculated. The position display become reversed as a result.
