Where I live (also a city in the PNW, with a lot of hills) bike lanes see heavy use during the weekday morning commute, and pretty spotty use every other time of day, and during the weekend.

Amsterdam is a different kettle of fish entirely. That's what I'd call "heavy."

Where I live there lots of little hills: the city is made of lots of hills. Even with electric bikes, it's really horrible to drive in the city.

But you see bicycles on the bike lanes, lots of bicycles. When it's summer time and when it's not raining.

Otherwise the people are all in their cars.
