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. This might be what it takes to inject more public interest into NASCAR.
By the way, I still like oval track racing, but I prefer short tracks. Again, more bumping and passing than what you see on the 1.5 mile or longer tracks.
