Speed limits + cars set an implicit speed minimum that is required for both safety and to not cause mad cars who are trying to go the speed limit. There's a reason you'll get pulled over for going 20mph on a US highway, and it's a legal oversight to have high speed streets that don't have minimums, or worse are designed to share with bikes even though the average bike won't hit a safe speed minimum.

So the legal maximum is ignored, the absent legal minimum is demanded. Doesn't this seem inherently dysfunctional?

The maximum is there precisely so drivers can respond to slower traffic, not so all traffic will conform to that maximum.

The whole point of the thread is that bikes and cars sharing the road with these sharrows is dysfunctional so yes, that's the point...

I don't know of a single place in the US where the maximum isn't treated as something to conform to. I've driven in the Northeast, South, and California. You'll get honked at for going noticeably under the maximum in all three places. What you describe just simply isn't the practicality of the US roads.
