So the Xfinity and trucks are going to a "chase format". Big deal, we knew that was coming, sooner or later. But this business with the trucks and the "green flag clock"? From now on, whenever the number of green flag laps reaches 20, they will throw a caution? No more "mystery debris cautions" in the truck series, I guess. Now it's "built in". So, what if there are 21 laps left in the race? They throw a caution on the white flag lap because it would exceed 20 laps? I'll bet there's a "special situation rule" for that one. Actually, more likely will be a rule that says a caution must be thrown when there are two laps left, if it's still green... What does this tells us about how NASCAR views its fans..? And are they right? If you go by the Race Hub show tonight, everyone, drivers, crew chiefs, commentators, thinks this is just awesome.
