There is a faction of folks that move through life challenging barriers.
For that select few, this behavior actually provides their income.
Be it the guy cutting in front of you in line, taking your slot at the 4 way stop, disregarding FA instructions, or bending other rules to hone his edge, he survives (and thrives) by taking the risks that the rest of us will not. The stuff we witness as a bystander are momentary sparks of reflection escaping from their psyche without a specific target or motivation. Imagine the experience if this guy wanted to put a particular person behind the eight ball...if your or I were his personal target.
Most ignore it. Some resent it.
I am the kind of guy that will drive a block to re-enter traffic on a light to ensure my right of way. I don't take the risks, I cherish control. When I enter traffic without a light, I bear the burden of the yield...on the light I wield command.
His sense of privilege is justified and empowered by lack of challenge from the human detritus he bears with as his societal tithe.
These people are different than the rest of us...they are better. Their time is worth more than ours, and the penny for their thoughts will cost you a quarter. If you doubt this, all you have to do is ask and they will be happy to tell you all about it.
On an aircraft, challenges can be problematic due to a variety of true wild cards. The view really is not worth the climb.
On the ground however...on a more stable playing field and legal environment, challenge is the key.
