> What TfL needs is having their planners cycle to work

This. Like the stories of having ancient bridge designers stand under their bridges, the people designing cycling facilities should be made to use them in order to improve their safety and usability.

I think for a lot of planners having a week where they are given a cycle orienteering challenge around a set of random points in a city would be a huge benefit. Give each of them a cycle dashcam and call it a data-gathering exercise.

Take a look at e.g. https://www.innertubemap.com/ , a third-party compiled resource of off-street cycle routes in Edinburgh. What strikes you as wrong with it? The fact that it's a set of disjoint small graphs and not a proper mesh, perhaps?

More use can also be made of name-and-shame: http://wcc.crankfoot.xyz/facility-of-the-month/

Btw, what you are referring to is the Hammurabi Code. Engraved in Babylonian by the Mesopotamians.
