I would prefer co-ordinate rather than police Klondike, but I agree with the principle.

The photography 'code' you mentioned has been in force since 2006 in London and adopted elsewhere.

Here are some guidelines I use.....

The thing to stress is NEVER intrude into the 'personal space' of the riders. With any modern compact camera, it is possible to get nice shots from some distance (just like my beach stuff) without getting into the riders 'zone of comfort'.

NEVER take shots of them undressing (unless you are some way away, and unobtrusive) and unless you look like a press guy, do not try to get poses yourself. I sometimes join in a posed session, from the sidelines though!
Best Place......
The best place to get shots is the start or finish (these giant rides always back up at these stages and riders have little choice but to pass the crowd slowly. I have ridden 3 times and girls who are very 'twitchy' at the start are often the ones who loose all inhibitions (on more than one occasion removing panties in the middle of the street) once the 'spirit' of the ride takes them over. Many of these girls are young 18-19 y.o. college students and when they see their mates stripping fully, peer pressure and adrenaline take over.

Ultimate Place.....
The very best place to take photos is to strip off and ride yourself BTW, I realise that some members may concider that a 'step to far', but once on the ride, you can take as many shots as you want and nobody will care. It is the attitude of the fully clothed (middle aged) males who shove a camera at a newly naked female that cause what few problems there are.
