I need to find a cheap gopro and start anonymously doing this with my bike commutes. It's neat to see snapshots of specific infrastructure being used at some point in a city's history and how that shapes the lives of normal people. There are certainly written accounts of life wading through horse shit in 1900 Manhattan but I've never seen a minute-by-minute account of how that person interacted with the psychogeography of the city in their commute. At some point it's going to be as interesting to someone as if we had HD footage of a medieval peasant going through their village.
edit: Also goddamn, Ljubljana makes me super jealous. My city has some of the best bike infrastructure in the US and it's nothing compared to this. I can't speak to the species composition but the urban forest is so much better. I would love to live somewhere like that.
