Here in Pittsburgh, we're a city of hills, bluffs, and narrow, winding roads, and listening to Waze help navigate me has led to $400 in repairs and 3 near accidents in the past 2 months by taking me through poorly maintained streets and roads so narrow that, while not legally-required to be one way, nevertheless make for perilous travel with few opportunities to turn around and try another route.

If users or editors could flag narrow streets and if an option was labeled to avoid these streets, similar to the options to avoid toll roads, it would be a major boon. I imagine the commercial sector would appreciate this as well so that you don't send a delivery truck down a road in which it may not be able to navigate safely.

I've been using Waze for years and I really like it, but the past couple months have really been pushing this to the forefront.
