Just a note on cameras on bikes, I think car dashcams are normalised and people don't care or act surprised when a car has one.
With bikes some people seem surprised or ridicule those who use or want to use a bike dashcam because there's a handful of people posting footage of incidents that they don't always agree with etc.
I was the victim of a hit and run, the van driver just drove off, I had no camera and it was in the middle of South Mall, I made my first report to the Gardai in my life because obviously this warranted it - 2 months later I get a call from Gardai saying they can't find any CCTV and dropping it.
So now I don't cycle anywhere without one for insurance.
My only issue is with people who post the footage on social media. Same goes for motorists who post dashcam footage online.
No issue whatsoever with someone using a camera (cyclist or otherwise) as a means of documenting and therefore protecting themselves from any incidents that may happen.
