It's because the bike lanes are great PR but bad for votes, at least in the short term. City leaders love the greenwashing effect, but in the short term the percentage of people actually biking everywhere is very low, so it doesn't make sense for them to spend a ton of time and money to do it right.

In a few years they'll get to put together a committee to discuss "learnings" and maybe they'll fix it if there are enough complaints, or maybe they'll just spend their time elsewhere as usual.

The US is happy creating laws for everything that are impossible to follow, but only selectively enforced.

Do you consider this insane? Your assertions that "everyone always must break the law" and "there are effectively no laws" seem a bit extreme. Ultimately, with any messy human affair, there is always going to be discretion involved, and I don't think implicitly codifying that is a bad thing. It does tend to work by and large. I've personally had much worse experiences with officials following the letter of the law than with them using discretion, but I admit I am not in any class that is often discriminated against.

That needs to be trained away by physically separating bike lanes from car lanes. Drivers (at least human ones) cannot safely coexist with cyclists or pedestrians unless there are actual physical obstacles between moving traffic and everyone else.

Waymo consistently stops in No Stopping zones.

Wouldn't it be safer for the bikers and people exiting on the bike lane side of the car if the bike lane was blocked?

And then bicyclists will hit the people crossing to the side walk.

That works for taxis but not for deliveries.

First of all, the walk would rarely be more than half a block. Bike lanes go down a small number of streets, so one can usually unload on an intersecting street. Not ideal, but ...

... bike lanes are not the only thing that creates this issue. Any road that lacks parking, with or without bike lanes, will have the same problem. Even when there is parking, all of the parking spots may be occupied. In both cases, people may have to walk a few blocks. While they may be grouchy about the lack of (sufficient) parking, you don't see many people blaming motorists for placing a burden on the elderly.

Finally, it is always possible to make accommodations. Having a carve-out for loading and unloading taxis will do far more for safety of everybody than letting people stop anywhere in bike lanes. It is also possible to have exceptions for people with disabilities, as long as non-disabled people don't abuse it.

Street side parking is fine. You can move the parking out a few feet and put the bike lane between the ordering and curb. Works well where I've seen it.
