Racer is a very open car simulator, meaning the usage of files for cars, tracks, scenes etc. are all documented, or at least should be, and can be fairly easily be created without the need for proprietary editors.

Beside that, it attempts to do well at the physics section, trying to create life-like cars to emphasize car control and doesn't cut back on realism in the interest of fun. If you've played Grand Prix Legends from Papyrus, you'll know what I'm talking about.
