I bought a connected oxymeter (viatom). I wore it overnight on my finger with the phone nearby. The graph on the app shows exact values through the night so you can see how many time oxygen drops and for how long. It's not quite as good as the real thing but should give you an idea, and it's cheap.

Assuming that's true, the most likely explanation is that they are working on Big Projects. Pothole maintenance is (probably) behind these projects, even though it can be done without affecting their timeline.
"Projects" (whatever that means to your municipality) are almost always contracted out. The maintenance crews maintain. Sometimes they do a little pre/post work for the big projects but mostly they maintain stuff. It's not like they're being pulled off a bridge replacement to fill a pothole.
That was me. I complained a lot about meetings, design docs, etc. I did not understand that the process of discovery is messy and what looks inefficient is not really. I expected sharper meetings, shorter docs etc. In retrospect I see my naivety but it took me too long to change my attitude.
Same with household appliances. Most of the familiar names are shadows of their former selves. Unlike in clothes though the quality alternatives are usually really expensive.
