Racing has always been the fastest car wins. With NASCAR it used to be you raced a production car body they even had templates to check the body lines. A few years ago NASCAR had a race where they all raced identical Chevys the idea was if all the cars were identical this would show who had the best driving skills. It was boring all the drivers did was drive around in a line and thats what NASCAR is today. All the same bodies just different stickers on them to resemble different manufactures, there are so many rules that the engines are basically the same, so all they do is drive around in a line. A lot of automotive ideas came out of racing but why invent new ideas when you can't use them, everyone is the same, everyone is a winner, boring. Thats why I quit watching anyway.
