You think mirror tilting is a CRITICAL button? Wow... What did we all do before tilting mirrors and back up cameras... No wonder we're such skilled drivers, we had to do it all the HARD way... You know, by asking our least favorite child to get out and help guide us... hehe... JK!!The buttons on the steering wheel are obviously considered critical, and for safety. The behavior of these critical buttons should always be consistent. What is the point in defending a bug? Some people just make me shake my head.
