That's possible, and I hedged a bit with an "if I understand correctly" because it was unclear to me how reliable the "coal roller" assessment was.
But if the bike rider's judgement was mistaken, the only consequence seems to have been that a driver of a diesel truck had ill wished upon them from afar. There's no mention of the truck getting reported to the police, and I speculate that the bike rider, as someone capable of recognizing the truck driver's good intent, might be cautious about escalating.
Nevertheless I'm sure that there will be those who continue to see the bike rider as an "unhinged" monster.
