Can't figure out why during my Indy Car seasons, when it is time to run the Indy 500, I only have a field of 25 cars! I've tried before the season starts, picking speedway cars thinking that would change it. I thought because I was picking Road Course cars at the beginning, that was the reason why. This new season I just started, I picked a Speedway car but still, a field of 25 during the 500. How do you get a field of 33 for that race during the season??
