Stewart would be right to want some privacy for his private life and be annoyed if the media started poking its nose in to matters that didn't concern them. However, the two time NASCAR Cup champion should know better than to use national TV airtime to make barbed comments that he just knows will tweak journalists' interest and leave them scrabbling for more details: if he'd wanted it kept private, he should have kept it private.
It's not as if the NASCAR media entourage isn't unusually respectful of its drivers' private lives - to an extent that raised eyebrows when no one reported on the breakdown of Kurt Busch's five-year marriage to wife Eva earlier this year. That was even though it was common knowledge in the NASCAR paddock, as Eva had been a regular attendee at races until the start of this season when she didn't appear for Busch's Budweiser Shootout and Gatorade Duel victories at Daytona. The media nonetheless decided that it was nothing to do with their coverage of the sport and simply ignored it.
The story only finally broke when Busch was joined in victory lane at Infineon Raceway by a woman later identified as Patricia Driscoll, who hugged and kissed him in the televised celebrations after he won the Sonoma road race. Several reporters felt in the circumstances that they had to explain the context of the images, as it was clear that the woman was not the well-known Eva Busch.
Subsequently the question asked was whether Busch's struggles early in the year were related to the situation with separating from his wife, while his mid-season boost was influenced by a happier personal life.
Now with Stewart's comment about his revitalised Chase form being down to dropping "dead weight" - if it really is related to his private life - it will make it increasingly difficult for reporters to agree that private lives are really none of their business in the future if they're shown to be hard-wired to on-track success.
