Honestly, since NASCAR modified the aero package to reduce the positive effects of drafting and allow the cars to pass, road course racing has become more enjoyable for this sport. I do think it takes more skill by the driver and the crew to set up and drive a car through left and right hand turns. .
Probably also explains why Danica didn't do well.
Even on a well funded power team (Andretti), Danica was average at best with the HEAVY aero and downforce Indycars...
