In reply to Tony Jones:
I don't have a camera but after one particularly bad pass on a narrow country lane I took the number and reported the driver to the police, their employer and the local council (was driving a school coach believe it or not). I knew at the time that nothing would be done as it was one persons word against another but if that person is a repeat offender and they get repeatedly reported then something might get done one day. I think it's worth reporting if you can get the number (which is easier said than done) even if you know nothing will be done.
It's a difficult one to deal with I think. Some people go on about what they'd do to the driver but it's not worth the effort. Personally it ruins my karma if I let it upset me and I don't like confrontation. Unfortunately close passes are an occupational hazard if you cycle, which is sad. And confrontation doesn't help. I think you dealt with it fine. It's easy to think about what you should have said or done after the event but no amount of debate would change the mind of someone like that. I think, if it's bad enough just get the number and report them.
I don't like the idea of having to mess about with a camera but then I live in a low population area so the number of bad passes are minimal. If I lived in a city I might think differently.
On a positive note, thank people who do good passes (there are some!). They might only be doing what they should be doing but it might make them more likely to do it again to another cyclist (which might be you again) and it makes you feel good.
Good luck in the future. Stay calm and stay safe.
