Steam now offers a playable demo for Trackday Manager, a simulation from Arctic Hazard Game Studio they call "a new category of skill based race car management in a multiplayer online environment." There is a post about restarting the servers for the demo, but no specifics about the demo's contents. Here's more on the full game: "Trackday Manager is a 3D simulation/manager multiplayer game where you are in charge of managing a racing team. You are not the driver but the team chief! You control your driver during races by issuing commands while monitoring the race carefully in beautiful 3D surroundings." Thanks Frans.
