Nascar's are built to do two things, go faster than hell and to be crashed. That hasn't changed since the first race EVER. Just because they stuck a mic in front of logano while he still wasn't recovered from having his bell rung and he said what he said isn't going to change much of anything. They will take the car apart and analyze what happened and what were the forces involved and make changes where or if needed. That is what they do.
