It depends what you're trying to achieve - I don't think the police would appreciate it and it certainly sounds quite patronising as well as being only from your point of view.
If you want more people cycling in Wales - (I only assume this)
then you need to connect with people in the community and people who are would be cyclists/current cyclists. Police aren't the guys who promote cycling (hence no point in you approaching them with it) and how people want to be treated surely would be down to motorists and other road users near you and educating people (this is by no means an easy task)
It might be more worth your while trying to find a local cycle campaigning group and work together with some people- like minded or not - it certainly would get you further in maybe achieving what you allude to above.
) would be to get to know the local beat bobbies and PCSOs, and build a good relationship with them, as a way of getting a chance to occasionally get a point across. Never to rant or lecture, but simply to be a sort of positive role model, who sometimes explains the sort of things like road positioning that so many people, cyclist or not, are unaware of. If you have a good relationship with a serving officer, you might also be able to occasionally make the point that some cyclists sometimes feel let down by the police after incidents - but you need to be on firm relationship ground before you start that sort of thing, otherwise you just come across as badly as those who rant about 'lycra louts'.Did you read my post?
I explained my experience, and the underlined link has nothing to do promoting cycling.
Yes, you said "I have always found the police to be adequately informed on cycle related issues." Clearly you must have been totally unaware of the Daniel Cadden case or you could not have used the word "always".
I agree in practice its discouraging cycling but the police think they are promoting safe cycling. YMMV
I think going to the Police is a big No, No from the sounds of it.
I didnt know so many people got so touchy over the subject. But if I do see any officers misbehaving badly on the roads, then I will be the first to complain and lecture them.

Matthew,
From your posting history it comes across that you are a youngster. If this is not the case, then my apologies.
After nearly half a century of experience I would suggest that your interactions with the police stay helpful rather than confrontational.
Complaining and lecturing them to thier face will not go down well. At best you will be told to proceed with your own journey, at worst you could end up down the nick on various public order charges. These will probably get dropped, but the net result is that you would have spent time at the convenience of others rather than getting on with whatever you had planned for the day.
Yep 17.
He sounds very well meaning but naive.
Fair enough, but I will still have a word with dangerous drivers (not close passes or RLJ of course).
While I'm not sure the idea was the best, it's intentions are honourable and don't deserve the grief he's been getting in response.
