Something about cyclists seems to provoke fury in other road users. If you doubt this, try a search for the word “cyclist” on Twitter. As I write this one of the latest tweets is this: “Had enough of cyclists today! Just wanna ram them with my car.” This kind of sentiment would get people locked up if directed against an ethnic minority or religion, but it seems to be fair game, in many people’s minds, when directed against cyclists. Why all the rage?
