It’s inconsiderate to take up space in a queue by not moving forward. People behind you would stop sooner, and if taking up extra space is exacerbated across more people, people who arrive at the end of the line continuously must stop sooner. Unless people are moving forward, this unnecessarily slows and lengthens the queue.

Granted, for cars, a car space or so between bumpers shouldn’t be that bad. It accounts for the chance an idiot at the back doesn’t brake in time and tries to start car-dominoes. I was taught to match the top of my hood with the bottom of the car’s wheels in front.

Hi, lurker here: what is/was LORD?

Could I think of the federation as like nations giving each others’ citizens a visa, or is that too off the mark to use as a metaphor?
