Much the same here in LA. City services are quite responsive. Actual potholes are almost always filled the day after they're reported, because they can be dealt with by one guy with a truckload of hot-patch.
But many road-maintenance problems are more complex, the result of underlying structural damage to the concrete road-base, which requires considerable work to fix. Filling existing structural defects with hot-patch
is a very short-term temporary fix at best, and may make the situation worse by diverting drainage to still-intact areas, causing further erosion.
The LA Bureau of Street Services publishes the following guides to help distinguish between simple potholes and damage requiring more complex repair:
How a typical pothole is formed and prepared

The second photo, above, shows the Anarchists making inadvisable repairs to a structural problem that isn't a pothole. Their efforts may very well make the ongoing erosion at that location worse.
It's a whole lot easier to make half-assed 'fixes' that make for good temporary cosmetics and politically-useful "optics" than it is to actually fix the problem correctly and permanently.
