An unusual suggestion for you: BeamNG.Drive. I wouldn't call it a racing game per se, the actual "racing" part is kinda limited, but it's got very realistic driving and crash physics, several different environments to race in (both track-like and open-world-like) and lots of opportunity for screwing around and modding. It's a PC game, though, and requires a strong machine to pull off not just the graphics, but also the physics calculations.

@HalJor@beehaw.org @gaming@beehaw.org Re:interesting environments I enjoyed wreckfest. Not open world though just laps and destruction derby.

TrackMania was just released on consoles and has a free to play tier. It's kind of it's own thing and might be worth checking out.
