It’s the same attitude. People who disregard traffic laws to drive faster think everyone is causing the problem, without thinking about how their driving affects everyone else. The guy who gets up and grabs his bag first doesn’t think about the 5 other people in the row who have to wait to get their bag, or that there are 50 rows of people that are all trying to do the same thing.

Fair enough. Most people mean, “If everyone drove 85 in the 55, ignored safe following distances, and didn’t waste time signaling and checking their blind spots, there would be no traffic.” Those people are not correct.

This is the same line of thinking as, “if everyone drove like me, there’d be no traffic,” (a phrase used exclusively by terrible drivers).
