Good for you, Ethan - I do it all the time. They are particularly unpleasant for utility cyclists like myself, especially on country roads where the edges of the road often collapse and fragment.

From talking to firends, family and work colleagues and from personal over the years, I think the quality of each council's highway fault reporting service varies enormously, some that respond reasonably quickly to both acknowledge your report and to do the work, whereas others don't send any reply (even an auto reply witha reference number) and take months to complete what should be urgent work.

Many councils' highway fault reporting services have exremely long-winded ways of reporting faults, some making doing so almost impossible (repoting potholes is normally the easiest), such as faulty streetlights of signage, as many expect you to give either an exact location and/or the number of the light/sign - very difficult when you're driving down a long road at speed. A few decent council websites have maps WITH the lights/signs marked on them (all you need to do is count how many lights from X landmark/junction), and you can also "mark the spot" for potholes, etc, which removes the need for reaslly details location wording...but many don't offer this service. As a result, some areas never get potholes, lights, etc repaired for years, as no council staff check (even if they're passing - unless its a major & obvious problem).

I think it also depends on the council whether they bother taking notice of "Fixmystreet" or similar - larger problems with road are only fixed at the whim of the council officials and/or councillors.
