These two things I've never been able to figure out and haven't seen anything written about.
For an oval track, I'd like to have a working spotter. I've seen third-party tracks which have a working spotter, but for the life of me I can't figure out what it is that activates it.
In addition, I'd like to be able to adjust the point at which the race goes green on a rolling start (or a restart). I've made AIW files for a few different short ovals, and while sometimes the start position is nicely off of Turn 4, other times it's disconcertingly right up against the s/f line (which can cause problems if people are accelerating too much like they usually are by then). Can't figure out what the determining factor is for this.
If anyone knows, these really should be put into one of the track tutorials!
