I find the opposite.
When I started using a camera I found I was less likely to tut, shake my head or in any other way react negatively to errant driver behaviour as I know that if the footage was ever viewed such reactions are likely to be used as mitigation by and on behalf of the errant drivers in question.
I've never posted any footage any where of close passes etc, I literally only have it in case something happens.
Sods law of course that the day I did get knocked over I didn't have it on.
If you are replying to mine then to be clear...I'm not suggesting a camera makes you ACT negatively, in the moment.
I'm saying it makes you hang on to negativity.
reviewing footage to see if you were in the right, prooving you were right for sure (you knew you were already) and getting upset all over again...hours after the incident has passed.
Then worse still, posting it and having others contribute toward an ever more growing negativity.
I found the camera offered too much opportunity for me to revisit stuff that I would have just shrugged off...and do today, that isn't really dangerous or bad...or deliberate.
Imagine having one record every moment of your life, every rude person in the street, every disagreement, row, poor experience. Then reviewing all that again each night.
Drive you mad.
If you are recording for a cause, a project or perhaps as
@gaz does, to try and educate, then I get it but In General, I found it a burden...emotionally.
