D: I rode my bike 7400 miles the first year owning it, (12 km single way commute and using it for going everywhere else as well).

100 miles is just two weeks of a 5 mile commute =/

I'm considering the average American adult bicycle owner. You would very much be the exception. Biking is generally considered a leisure activity, not for commuting.

Everyone should be like you, but the infrastructure doesn't support it yet in most cities. Safety in a fully A -> B network is required. Driving more micromobility traffic will cause infrastructure changes in the long run

You're correct, but 5 miles/yr is a rather low average, no? That's a single commute.

Bikes are much better in general, especially electric. However, if we are comparing to usage today, a tiny tiny fraction of bike owners commute. Most adults will probably take it out for a ride less than 10 times a year, and for a super short rides. I don't have any stats, just based on observations.

I am all for shared micromobility everywhere. Would love to see a healthy mix of scooters, bikes, and mopeds on nearly every corner (in dedicated converted car parking spaces)

However, somebody who is commuting daily on their bike is replacing it and/or most of its components a lot more often than once every 20 years.
