New rule in Nascar

I am sitting here, watching the Nascar race in Dover, and I notice that they have a new rule, and I for one am really liking it. Racing back to the yellow has been a big thing in Nascar for a long time. If the leader slows to let a friend or teammate, or even anyone else, by him on the track, there was previously a gentleman's agreement that no one would pass. This is not a rule, only a recommendation. Jeff Gordon passed the leader last week, and unlike the views of the person in chat, they did not pat him on the back and make his actions a new rule, instead they ruled what he did was not right and have now made a rule that when the yellow flies, that is how people sit under yellow aside from pits changing the order. Also, the first lapped car gets the lap back. It has gone well, thus far.
