Good point - though my personal feelings on it are that doing that is tagging for the renderer and raises the risk of error in data entry and harder to update, since you have to think about the inverse of what’s actually posted on the sign! Putting in what’s on the sign means that any renderer could also theoretically reproduce what is actually on the sign too, for any reason that might come in handy.

Thanks so much. I had no idea about OSM Help!

Definitely true. There’s also a rainbow bike path in the Netherlands. https://youtu.be/sSHOQQkAwk4

Maybe a colour or design tag? That way bike paths could also be tagged as to their colour. E.g. red, blue, green depending on what they are.

Cool, I’ll do that, Pieren, thanks.

FWIW, the car park appears to be run by the local council, with their logo posted on signs, etc. rather than privately owned.

Here’s a picture of the one in Twickenham

+1 for OSMTracker, I like the UI for adding notes/amenities to your tracks.
