I am actually working on this again; had taken a break to do a variety of things on Steam, and the project was held up by some plugin and code issues that I resolved as of today. The game is back on track, and i'll be putting up more regular updates in the next few days.
It's about 75% complete now; adding in-race display/decisions, save games and between-seasons progression is all that's left to do.
Setting up sponsors, tracking stats, simming races, building new cars, driver injuries, driver training, special random events, setting up drivers and crew chiefs (and their contracts) is all finished and working well.
