Yes, yes it is a low effort comment. And it is exactly what I was trying to preempt. It adds exactly zero to the conversation to say "but the law" or "but drivers ed" or "but some proverbial rule of thumb".

For better or worse neither your fantasy of how people ought to act nor the letter of the law is reflective of how the overwhelming majority of the human population operators motor vehicles or expects others to. Is it ideal? Probably not. But it's a decent balance between being somewhat prepared for the expected traffic oddities, leaving margin for some subset of the unexpected and efficient use of road space.

I'm sure this will be an unpopular comment because there is no shortage of people here who think humans adhere to laws the way a network switch adheres to its configuration but the reality is that there is not perfect alignment between how reasonable traffic participants behave and the letter of the law.
