Dale Earnhardt Jr. put his foot down on keeping NASCAR a predominantly oval series. He argued that road courses have fallen short of what the fans have come to expect.Go Bowling at The Glen saw the least passing, while racing was stagnant on equal tires. The aero deficiencies of the Next Gen Package were on full display, as many struggled under dirty air.The only exception to this ordeal was Shane van Gisbergen.

He previously finished 16 seconds ahead of the field in Mexico City, further underscoring the lack of competition on road courses.On the latest episode of Dale Jr. Download, Earnhardt took a shot at the dismal state of road course racing."In NASCAR we expect lots of passing. We expect lots of battles, we expect contact, we expect door to door. That's our expectation because of the last 75 years of what we've seen when we come up on a road course now and we don't see what we expect. We're not willing to allow this type of product to be normalized," he said."My opinion on how many road courses we should have is going to be in the minority. I like two road courses. I like Sonoma. I like Watkins. Looking at NASCAR in the 75 year history, it was born out of the dirt tracks and the short track half mile style facility. It was an oval series," he added.The Cup Series calendar has one more road course at the Charlotte Roval. Dale Earnhardt Jr. also mentioned how fans would rather enjoy Charlotte's oval configuration, seeing how the event appears towards the end of the playoffs.
