Which really puzzles me, given their transit infrastructure. Do they still lack cell coverage in the subway? Smartphone on transit is what killed my cycle commute. I just love those sleepy minutes idly indulging in some light social media infotainment before the day really starts.
I just love those idle minutes in the tube when no one can get ahold of me for once.
It is not that everyone is cycling, just a lot of people. Many (most?) people still choose the U-bahn or tram (on the east side).
I think that it is a question of lifestyle. Instead of choosing hot and moist U-bahn, you have a refreshing ride on the bicycle. Especially when the distances are short. Well, this is just a hypothesis.
