Nascar has forgotten very little. Rules in racing have had to be made, some forced to be made. For instance in the 50's why did they outlaw fuel injection, or in the 60's, why did they make an engine displacement rule, or out law certain cars. It happened as recently as the 90's with one of Evernham's cars or why was certain popular engine architecture (SOHC or DOHC) outlawed?. If you don't know the answers to those questions and why it was done, how the sport has evolved and continues to do so, I suppose some of this stuff seems new or strange. It's racing, it isn't isolated to Nascar but all series of racing and it has been going on for years. Teams will continue to try to work out side of the rules or make stuff that will force the sanctioning body to make more rules. This ain't anything goes cowboys.
