A) This is not at all unusual. Mark was racing for something far more significant than the difference between 34th and 35th in the race. Almost every driver in the top 25 will make such comments at some point in the season when a part timer is near them sliding all over the place. Unbunch the undies; it happens every race.
B ) Mark is and has always been the type driver who, when laps down, gets out of the way and allows those racing for something that matters to do so without having to dodge him. Unlike some on the circuit. Mark simply expects the same courtesy in return. It's been his undoing before too.
C) At least it wasn't as bad as Jimmie Johmson's whining about wanting someone he was racing for position to move over and let him by, as has happened on numerous occasions.
Dislike Mark Martin if you choose, but if you wish to save yourself some egg on the face find something better than this. Mark is a consumate professional, a gentleman, and one of the most respected drivers in the garage area. He is also perceived as a whiner from time to time; sometimes I agree, sometimes not depending on the circumstances. In this instance, I don't agree. Feel free to form your own opinion.
