#4 Shorten races
Whether NASCAR fans want to admit the cold, hard truth or not is up to them, but its starting to become obvious that the sport needs to cut costs. While that might sound like a bad thing, especially since it means less racing action throughout the weekend, it also creates more of an incentive to be aggressive in the shortened race.
NASCAR will only be able to cut operating costs, broadcast casts and anything else by shortening certain races, which will be great from a monetary standpoint. In the end, its probably not the ideal solution from a NASCAR fans perspective, but it could do a lot to make things more exciting and competitive every Sunday.
