As they prepare to begin the Chase for the Cup with the Sylvania 300, top NASCAR executives are worried about the financial impact another season free of horrible injuries could have on the sport. 'Every day a car doesn't flip over or a driver isn't set on fire, NASCAR loses money,' chief marketing officer Steve Phelps said Monday, adding that the main reason fans say the sport hasn't been the same since Dale Earnhardt, Sr. died in the 2001 Daytona 500 is because no one has been killed or maimed in that time. 'Of course, we hate to see anyone get hurt, but then again, we have to put the needs of the fans first.' In related developments, NASCAR officials are expected to announce changes to the Car of Tomorrow that include eliminating seat belts, a top speed of 300 miles per hour, and special design features that make you look like a girl if you wear a helmet while driving.
