I did read on another site how Nascar is actually going to let the drivers have some personality this year, as long as it doesn't get out of control.
Also, I see the may be starting races earlier which is something many people wanted to see. People won't wait around until 4 or 5 pm in the east to watch a race in the summer (especially if its not a premiere race or track). Too many other things available to do. If they do indeed go back to noon or 1 pm starts, race would be over by 3 or 4 pm leaving the rest of the afternoon/evening for outdoor activities. Earlier starts would also help them during football season. The key is to get your audience interested before the football game starts. Once viewers are into a football game, chances are unlikely they will switch off to watch Nascar.
