Tony Stewart may have figured out another issue in his inability to master restrictor-plate racing: no one on the track is helping him.

Or no one wants to help him.

NASCAR changes leaving Tony Stewart "timid" and "confused?"

Fox Sports reported that Stewart is upbeat about his chances of returning to Daytona International Speedway for Sunday night's Coke Zero 400.

He is coming off a 12th-place finish at the Save Mart 350 in Sonoma, Calif., last weekend. The performance, which included an 18-second pit stop that dropped him out of the top five and prompted a profanity-laced tirade, as reported by Sporting News, still was his second best performance of the 2015 season.

He said that at a race track like Daytona, all drivers have a chance to win.

"Everybody has got a shot at Daytona," said Stewart, according to Fox Sports. "We've been in that position before and have actually been able to take advantage quite a few times. The biggest thing is it gives you confidence that you've got a shot."

That is the same thing he said about restrictor-plate racing.

"I wish I could explain it," Stewart said. "I'm certainly not any happier about it than I've always been, but we have had a lot of success at restrictor-plate tracks, especially Daytona. I'm glad we're halfway decent at it, but it's still always frustrating when you have to rely on what everybody else does. It's not what you do. It's what you do along with somebody else who decides that they're going to follow you and help you. That's the part that frustrates you as a driver.

"The great thing about restrictor-plate racing though is that 43 cars all have the same shot at winning the race, but again, that's also part of what makes it frustrating, too," he said. "It's just being at the right place at the right time."

So does that mean that nobody is helping Stewart or that he is just in the wrong place at the right time or right place at the wrong time?

He may discover the answer at Daytona on Sunday night.
