The pit road speed limit at Talladega is ridiculous. Those cars come off the turn at 190+ MPH. Then they are forced to slam on the brakes to avoid a speeding penalty. There have been several accidents because of cars losing control over this. Brad Keselowski almost wrecked, spinning 180 into his pit box. It made the highlight reel because it looked cool. It could have just as easily been posted as an, "over 18" video at Live Leak, if he had spun past his pit box, and pinned another crew member between his car and the wall.
This is a classic case where the cure, ("speed limit"), is causing the very problem it is supposed to prevent, (pit road accidents). Between the bunched up "racing", along with the stupid pit road speed limits at that track, it's causing far more danger than it's preventing. It's the same at Daytona. They've been lucky. If Austin Dillon had gone roof first into the catch fence, the fans would have been sprayed with his body parts. Instead, by going in bottom first, it tore the engine and transmission completely out of that car, and threw it clear across the track, into the infield. That car went from 190+ to 0 in 30 feet.
If that engine and transmission had instead cartwheeled through the stands, it could have killed dozens. Common sense dictates the tighter these cars are forced to race together, that more, larger, and more violent wrecks will be generated. Years of restrictor plate racing has proven this over and over. It's only a matter of time before someone, (or several fans), gets killed. Creating more carnage, while at the same time being lucky, is not the way to build a, "safety record".
