I have attended all 20 Brickyards and sat in turn 3 for all of them. There are three points in which to look. 1. It seems to me that it use to take 2 or 3 laps for the cars to get sorted out after a yellow. Now the cars seemed sorted out by the time they reach turn 3 and most certainly by the time they are back to the start / finish line. I look at the "Chase" as one one of the reasons. Since the implementing the Chase NASCAR racing has been suffering a little more each year. 2. A new car this year, the Gen 6. As indycars fans have seen the 2nd year of the DW12 has produced some of the best racing the series has seen in years. Availibility of new parts were slow for NASCAR teams causing delays in the development of the new cars for some teams. 3. Speed. The faster they go the harder it is to pass. Restricted cars at high speed tracks makes for more competition. Record passing at indy the past two years and a lower bugeted team finishing 1 - 2 at Talladega this spring all due to restricted horsepower. I wonder if the straights at Indy would make for some drafting and increased passing if the stockcars were slightly restricted. The more you use aerodymamics to achieve speed, the more you need the aerodynamics to stay consistant to maintain that speed. Hence being out front and clean air is so important at high speed tracks.
