Tony Stewart understood why Brian Vickers wrecked him late in Sunday's race at Infineon Raceway. But he's not sorry for starting the tit-for-tat incidents that began when Stewart intentionally spun Vickers earlier in the race. "I probably had it coming because I dumped him earlier, but I dumped him because he was blocking," Stewart said. "If anybody wants to block all year, that's what I'm going to keep doing, so they can handle it however they want." That's a standard refrain from Stewart, who has grown increasingly frustrated with a lack of on-track etiquette. He complained after last week's race at Michigan that drivers were "a bunch of idiots" on restarts. "I've been complaining about the way guys have been racing all year," Stewart said. "I like Brian, I'm not holding it against him at all. I don't care if it was (teammate) Ryan Newman, I would have dumped him too. If they want to block that's what is going to happen to them every time for the rest of my career." Read more: http://sports.espn.go.com/rpm/nascar/cup/news/story?id=6707283
