Again, we can agree to disagree on this. I'd do the same thing again tonight should I be passed dangerously. We're not talking about an irate cyclist confronting motorists with the intention of unloading a piece of their mind or verbally abusing them... I firmly believe that that vast majority of close passes are the result of ill-judgement, a lack of anticipation, or a lack of understanding about how much room is acceptable, not a malicious attempt to cause harm or distress.OP's mistake was to confront the driver which could have meant that things could have got ugly, possibly very ugly indeed. A cyclist is never going to come off better in these situations however much you think you can handle it. Best avoid and move on.
Maybe that's a naive view, but what's going to stop them doing the same thing over and over again and possibly causing an accident unless they're told that it's a problem?
