Why doesn't anybody take the Cope twins seriously?

Many drivers from famous families have try to make their mark in NASCAR and have not been considered a joke like the Cope twins. Drivers like Kerry and Dale Earnhardt, Dale Jarrett, Steven Wallace, and Bobby Hamilton all try to follow in the foot steps of famous family members. Some were successful and some have failed, but all these drivers were taken seriously and given the opportunity by the NASCAR Nation to prove themselves on the track before they were judge by the fans if they were worthy enough to drive in NASCAR. So should the Cope twins be given the same respect or is it acceptable to dismiss them because they are pretty, blond, and female?
