Horse riders get it and can ride 2-abreast all day.
However, it has been a long time since horse riding has been a major form of commuting transport. If people commuted by horse I think things may kick-off a bit more.
Fair point. I was just thinking that respect on the roads shouldn’t be conditional or based on volume of traffic, but then I’m expecting too much from human nature. Pressure on space turns people tribal / all protective-defensive and more likely to be aggressive.
