It's a small example of when a large mass of people gets dumbed down. There are several consequences of a dumbed down population. One of those is "follower-pack-belong-herd" mentality. An example of this is a 2 lane road or highway where you have one car going 45 in a 55mph zone in the right hand lane and there remains 15 cars behind that car looking Dead Straight Ahead right behind the slow vehicle and those people aren't even considering getting to the left lane and passing. They are Following-Fitting in-Waiting to "be told or instructed", and then of course, one of those cars in that line thinks for themselves and moves to the left lane and goes around. Another example of this entire mentality that actually goes along with your parking situation is the Fallacy of "playing to the audience" when debating or arguing. This will come in the form of someone giving their opinion and starting their statement with "We, or Tell Us". They are pointing out they belong to the herd, and you don't (so something just surely be wrong with you) and in that situation, they even elect themselves to speak for the herd. All of the above including your example is part of this dumbed down population of which one of the consequences are "Follow, lump in, Herd, Sheep."
