Last week there was a nasty wreck involving several cars on my main route to work. Consequently there was a ton of glass all over a 50 yard stretch of road with most of it being in the bike lane.
Yesterday I visited the city's transportation department's website and sent them a note informing them of the glass and debris. I came to work this morning to an email letting me know that they have dispatched a sweeper to the area to clean it up. I was surprised and delighted at their very timely response.
