I was wondering if there is an idiom in English language such as e.g. "road ranger" or "road sherriff" to describe a malice person who blocks other drivers from implementing a zipper system, to relieve the traffic congestion when one of the lanes is ending (common practice in Europe) as shown here: https://www.youtube.com/watch?v=2HOD0N2at0c
Alright i looked at the video, and i think that scenario is a bit different from what is described in the question.
: a driver of an automotive vehicle who obstructs others especially by occupying part of another's traffic lane
Definition provided by Google:
a member of a self-appointed group of citizens who undertake law enforcement in their community without legal authority, typically because the legal agencies are thought to be inadequate.
It doesn't have to be a member of a group though, as Cambridge Dictionary says:
a person who tries in an unofficial way to prevent crime, or to catch and punish someone who has committed a crime, especially because they do not think that official organizations, such as the police, are controlling crime effectively. Vigilantes usually join together to form groups.
Only thing that bothers me is the fact, that it's not enforcing the law, because the zipper system is absolutely legal and logic, it's just new enough for people to think it's a selfish action of those who don't care about others
One who drives as close to the next bumper as possible. Contrast with tail-gater, but tailgating is typically considered to be done at higher speeds. And bumper hugger sounds less derisive.
I've never really heard it, but outside of some much more colourful language i've never really heard this described.
Its kind of used in an article here: https://beta.theglobeandmail.com/news/british-columbia/nothing-divides-drivers-like-the-zipper-merge/article33813809/
My justification has always been that in all but a few cases the obstacle ahead is clearly visible and, since I am not able to travel through solid matter, I must move over – and the sooner the better because it reduces the chances of encountering a bumper-hugging, cursing anti-zipperite such as myself.
If you consider that there are many people who aggressively merge, you might also describe this person as the winner in a game of Chicken:https://en.m.wikipedia.org/wiki/Chicken_(game)
The game of chicken, also known as the hawk-dove game or snowdrift game, is a model of conflict for two players in game theory. The principle of the game is that while it is to both players’ benefit if one player yields, the other player's optimal choice depends on what his opponent is doing: if his opponent yields, the player should not, but if the opponent fails to yield, the player should.
In this case, you could describe them as a hawk.
