It's great that Lewis was honest during his interview. He felt the need to tell everyone what he truly thinks of the stewards' descions.
Moreover, one of the well known quotes by Ayrton Senna was "If you no longer go for a gap that exists, you are no longer a racing driver." Sure, some attempts by Lewis to pass drivers didn't go so well, but that is all part of racing. You take every oppourtunity to overtake you get, whether it goes well or not.
