This is a photo from two years ago, i stood there for a good minute wondering how the hell and why this weird cycle path was there. It is in southern France, on the climb to Col d'Ecre, bit north of Nice.
Take a guess, i finally fully understand.

Best guess, it's for allowing cars to pass?
Nope.
A hint: These two poles and the one with the solar panel make sense of the whole thing.
Hmm, something like a chip timing station so you can time your climb?
Presumably there would be similar ones at the bottom and top also, and perhaps at other points along the way.
Wait a second. There might be something further down and up the hill that i have not fully understood yet, so this could also be a timing machine, i am not sure. It's not the function that i'm looking for though.
No timing, but this is getting close. There is nothing further down this climb, but this infra apparently also exists on a few other climbs in the area.
I have posted the solution already, but you can keep playing.
