Two lane racing: Low Lane (14 degrees) is more banked that the High Lane (10.6 degrees). I tried to encourage drivers to run the high line.
Grandstands: An actual area for fans, with a few on-lookers.
Catch Fences (currently straightaways only): Like my next point, I was trying a realistic feel.
Pit Boxes & Crew Chiefs: I thought it would be nice to give it a "realistic" feel, so a pit box, with crew boss.
