What are you on about? I prefaced my post quite clearly. This is nonsense.
> People burn coal while passing cyclists. Why? You yourself say that not all cyclists are preachy.
Because there is a perception that cyclists are like this. Whether it is true or not doesn't matter. If a group of people don't police the most extreme members you are defined by those members.
BTW mountain bikers/bmx don't generally have the same poor perception IME as many other cyclists because generally the attitude is generally different.
> Your accidental and short release of dark exhaust caused by driving an old vehicle does not fit the definition of burning coal. City busses where I lived in the 1980s emitted a lot of exhaust. That was simply bad emissions control, not rolling coal.
Other than it not being deliberate it was "rolling coal". To get the black soot you need to just have poor combustion of a diesel.
This was what was happening because I had to push the throttle to the limit so the engine didn't stall. For all intents and purposes it is exactly the same thing as there was incomplete combustion of diesel and therefore lots of black smoke coming from my exhaust.
