Ok I've looked into things a bit.
There are no sector times available for the rally type tracks that I can see. So the track would have to be broken into sections, either manually at certain specific points on the track by someone, or by dividing the track up into e.g. 5 equal parts.
Also the ghost cars features are not available for these tracks.
This could be implemented in some form. What would be the idea - different lap time tables for each sector, with standings points for each sector and extra standings points for the overall fastest time? Or something else?
Name - Sec1 - Sec2 - Sec3 - Sec4 - Sec5 - Total - Points
Drv.A : 55.2 . 40.9 . 49.6 . 56.3 . 44.5 . 4'06.5 => 220
Drv.B : 44.2 . 40.9 . 49.1 . 55.4 . 46.7 . 3'56.3 => 190
Is there much interest for this sort of thing? A lot of players doing rallying in AC?
