NR2003 has a few failed projects that I remember why they failed. So I'll list them here.
One of the tracks I once made for NR2003 that didn't even get hosted was a 3-mile, figure-eight track. The track's racing surface was 100 feet wide and while I forgot how much banking it had, I remember that it could be taken flat-out without a restrictor plate. I don't remember why I abandoned the project though, or whether it used Chassis 5.
I once made a drivable road course track for NR2003. I didn't even finish modeling-in the walls that were supposed to surround the track, but I got close to that. The track was never given a public download, but it featured a 315° clothoid turn that was challenging to take. I don't remember why I abandoned the project in the first place, but I do know that I won't go back to it simply because it's in the way of my own racing simulator.
The TCR Raceway was supposed to be a 1/4-mile oval. The track was to be banked 12° in the corners and pit road wrapped around the outside of the track. This track was very similar to Dodge Raceway Stadium from NASCAR SimRacing in terms of overall layout, but was much shorter and had fewer stalls. However, I could never get the AI working properly regardless of whether I used "Butter's Rule". I also once had a version of this track for rFactor 1. I have since deleted purged the track from my computer and from all hosting sites.
