Dale Earnhardt Jr. is back in the Bojangles Studio for another edition of Dirty Air. All three of NASCAR’s top series were in Austin, Texas this past weekend to compete at the Circuit of the Americas, and there was a lot to unpack:

• Roaming scooter gangs
• Connor Zilisch’s eventful NASCAR debut
• What caused Marco Andretti’s rear end failure? 
• Austin Hill vs. SVG
• What NASCAR milestones are tweet-worthy? 
• Cup race winner William Byron calls in
• It’s time to bring the curbing back at COTA
• We need to revisit the NextGen road course package

During the Ask Jr. segment of the episode, listeners sent in questions regarding:

• Dreaming about racing
• Weirdest items every autographed
• Tattoos
• The best neighbor
