I've not be using cameras for as long as you, so I will acknowledge your personal experience.
But I have to ask, the "close encounters" that you have, is that because you have reacted in some way? Shouted, told them you're going to report them, that sort of thing? I've done that in the past, but now avoid it. So all they will get is a a letter from the police. Sure, I have to say I will attend court if required, but that's it. So unless the driver can remember when they close passed a cyclist, what that cyclist looked like, and then attempt to track me down, I don't feel there's anything to worry about.
no, the drivers who have come after me like that, not really sure how to word that better tbh, obviously I wasnt far from home when it happened, but I did nothing other than just ride in prime on the road, didnt react or shout or swear or do anything when they close passed me, and they took enough objection to some part of that, that yes they would then cancel wherever they were driving, just to follow me to my front gate and then we'd have a fruitless 5min debate about it.
I have absolutely challenged drivers very strongly sometimes on the road for their behaviour towards me, I refuse to be bullied or kowtowed by them, but Im not really worried about them so much, as most of them are looking for that reaction/argument in the first place I think.
but I dont know how drivers react to a NIP to a close pass. most drivers dont seem to believe theyve done anything wrong anyway even when I challenge them, and I find it hard to believe theyd just accept points or the cost of a driving course without question, without pushing back in someway. and so yeah it crosses my mind do I want to open myself up to that potential pushback by reporting them
id say 90% of my close passes happen on my commute, so its something Im regularly doing in the same place at the same time, frequently, and there aren many cyclists around, so it does mean I feel more vulnerable than kind of just random road interactions with hundreds of cyclists around, even though most of the traffic I encounter seems to be entirely different each time from my perspective
it is just a factor I think about and weighs more sometimes than it shoud
