Many cities would stop functioning if everyone followed traffic laws — the whole system is built around drivers ignoring many rules. Businesses need deliveries to be unloaded and delivered. Customers need to get where they are going. And many cities do not actually leave space for loading and unloading.

There’s a related issue that will become apparent as more cars drive themselves and take responsibility for their actions: speed limits. If traffic engineers want cars to drive 75mph, they should set a speed limit of 75mph.

Yes, but I hope we can both agree that if Waymo stops where it's not allowed, it's waymo's fault, not anyone elses, and definitely not the fault of traffic enforcement or lack of.

Like you said - if traffic engineers wanted people to stop there they wouldn't have made it a bike lane.

I don’t really agree, at least not in a broad sense. If Waymo refused to stop and circled the block many times instead, and if Amazon trucks did the same thing, and taxis and such did the same thing, and the big trucks that deliver restaurant supplies did the same thing, etc, then bikes would be able to use their lanes freely but no one else would get much done.

We live in a world where many useful things require people to break rules. Is it the fault of the rule breakers or of the rules?

The rule breakers are responsible for breaking the rules. I thought that's a very simple uncontroversial statement.
