I am a little on the fence with him. Used to think he was just an attention seeker but he certainly does more harm than good, especially catching people using phones while driving.
Can we please not use the term ‘self entitled cyclist’ as it is just plain wrong & inflammatory (sorry Tiggers, I agree with you on most things). Cyclists generally just want better infrastructure & to be treated with more consideration by drivers, that is all. If there is a group that is ‘entitled’ it is the not so humble motorist, entire cites & road networks are built for their exclusive use.
I think the most eloquent person on this topic is Chris Boardman, he has suffered personal tragedy also but it very level headed & cogent.
Quite a few of my friends use cycling cameras now, mainly for self protection in case anything happens. Some police forces will act on footage but most don’t, they also seem to look down on cyclists swearing when someone nearly kills them; all very odd.
