Even before several drivers crashed during Sunday's Cup Series race at Charlotte Motor Speedway, there were numerous crashes during practice on Friday.
Kyle Busch, Dale Earnhardt Jr., Brad Keselowski and David Ragan all crashed during practice, and Earnhardt said on Periscope after the race that the PJ1 traction compound on the track is to blame.
"It was a really a hard day as a driver," Earnhardt said. "I know you guys want it to be hard and it should be hard, but it was hard for all the wrong reasons today. Hopefully they don't use that PJ1 spray on any other race tracks for a while. I think they need to research that a little bit more before we use that again."
Earnhardt finished 12th, but other drivers had difficulty on Sunday. Busch crashed into the wall, while Ragan and Danica Patrick were involved in a big crash late in the race.
"Had they not put the stuff down on the track, we would have been driving all on the fence and everything trying to find grip and hauling ass up there, but we just couldn't get up there and use it," Earnhardt said.
"I was real disappointed that they sprayed that stuff down and it didn't work. It's easy to say that after the fact. I'm not trying to get too hard on the racetrack, but man I want to see this place see its real potential."
The traction compound was applied unevenly, which resulted in drivers losing control and crashing into the wall. It's certainly an issue NASCAR officials will need to monitor closely before it continues to have a negative impact on drivers and races.
