Auto racing: Tony Stewart more than ready to leave NASCAR

There was a twinge of nostalgia in Tony Stewart’s voice as he was inducted into the Sonoma Raceway Wall of Fame.

Then his mood quickly turned as he talked about the reasons he’s retiring from NASCAR competition at the end of the season.

“I’m ready to go run stuff that makes me happy, and driving a Sprint Cup car does not make me happy right now,” Stewart said Friday. “A lot of things have changed. The atmosphere has changed. There’s so much stuff in the garage area that’s changed that it was time for me to make a change with it.

“I’ve dedicated 18 years of my life to this series and it’s done great by me – I’ve made a great living doing it. But at the same time, there are other things in life I want to do other than be at a NASCAR track three days a week for 38 weekends out of 52 weeks a year.”

Stewart is a two-time winner at Sonoma in California, and Sunday’s race will be his final one on the road course.

Part of Stewart’s comments Friday reflected his frustration with practice, which ended in an incident with Jamie McMurray.

Stewart flipped his middle finger at McMurray because he thought McMurray had ruined his lap.

“Some of the things these guys do nowadays doesn’t make sense,” Stewart said.

“When we had Dale (Earnhardt) Sr. and Rusty Wallace and Dale Jarrett, they were able to get their arms around these guys and get them to listen and make sense. There’s really nobody here that can do that anymore. Everybody is out of control.”

But Stewart wouldn’t bite when asked how to change the attitudes of the younger drivers.

“I’m not even going to talk about those guys,” he said. “It’s not worth it.”

Newgarden cleared

IndyCar has cleared Josef Newgarden to race at Road America in Elkhart Lake, Wisconsin, on Sunday, two weeks after breaking his right collarbone in a scary crash at Texas.

Newgarden got the medical clearance after being evaluated following each of two practice sessions on Friday at the rural Wisconsin track.

He got hurt on June 12 at Texas after his car slammed on its side and slid along the front-stretch wall with the top of the cockpit exposed.

Newgarden and Conor Daly will not be allowed to participate in the Aug. 27 resumption of the rain-delayed Texas race.

The race was still under caution for the crash involving Daly and Newgarden when it was stopped because of more rain.
