I've already mentioned this topic in the server at IndyRC and Charlotte so I'm just reinforcing some noteworthy points.
Entering the Cup Series, we had made a few changes to the league rules page. We recommend reviewing them. The most important of which are the double-file restarts at the end of caution flags. However, we also updated the rules page as it pertains to pit road entrances, pit road exits, and some other caution flag details. Prior to Cup, we still had it technically on record that drivers are required to use the apron on pit road entrances, even though we had changed the actual policy in practice. So, now the entrance rule is changed for good, in an official sense.
On that note, I'd also like to commend the field for the solid performance at Charlotte in our first race with double-file restarts. Technically, we also had the rule to start the season at IndyRC, but we didn't have a caution in that first race!
