Every few years NASCAR jiggers with its points system, and this year — starting with Sunday’s Daytona 500 — there’s another new system to figure out who gets to the playoffs. Will it make the racing better? “We have yet to see, but I’m sure it will,” she said in a phone interview last week before she took fourth in the Clash exhibition race Sunday at Daytona. [...] she said she’s “super-optimistic” about the new season, especially because of her team’s switch from Chevrolet engines to Ford. Previously, Stewart-Haas got its engines from Hendrick Motorsports, putting Tony Stewart’s team in a secondary position behind Hendrick’s racing team. There won’t be any bonus points for leading a lap or for leading the most laps. Drivers can earn bonus points, now called playoff points, in the 26-race regular season and carry them through the 10-race playoff, which is no longer called “The Chase.” With breaks between the stages, Fox and NBC will get built-in chances to run commercials. NASCAR apparently is trying to appeal to younger fans, who have been turned off by races that drag on too long. Other racing series, like IndyCar, Formula 1 and drag racing, have experienced gains. “In society today, with the way we digest news, the way we get it, the pace that we get entertainment, we have very little attention span,” she said. Drivers and crew chiefs will take more risks, she said. Whether it be risks in strategy or even a risk right before the end of the segment to try to get the win, yes, I think you’ll see more risks be taken. Patrick, 34, remains one of the best-known drivers in NASCAR, and in addition to her many commercial ventures, she has a new enterprise: wine producer.
