Probably because enlightened centrists who elect republicans and pat themselves on the back for it aren’t real progressives and are really just full of shit

One word: Puritanism

This is an amateur move in heavy traffic under 30mph (let alone any other speed: for safety reasons, the stopping distance should be about 3 seconds: count when the car in front passes something and it should take you 3sec to get there)

Frantic stop and go jamming on the brakes? No car space? Tense on edge? Ha, amateur move.

Real kings of the road leave space, sometimes even 10-20 car lengths, so as to time acceleration and deceleration as precisely as possible, maximizing optimal usage of each.

This saves brakes, transmission, engine wear, prevents accidents, and reduces traffic, so don’t get uppidy when you’re behind a king and you’re jamming on your brakes like a chimpanzee stuck in peanut butter at the circus

Someone wants to cut in? Go for it, doesn’t make a difference to a king of the road (or any other gendered or non gendered royalty)
