Does anyone know where I can find statistics and stories on the dangers to peds and cyclists from double parking?

Many people in my neighborhood double park, and when I tried to explain the dangers of this to a parents' group many members became angry, insisting that they "need" to double park and that police should overlook it, and that this doesn't pose a significant danger to peds, cyclists, or those waiting for the ambulance stuck behind their unoccupied car.

Any resources? I googled but haven't found anything specific...
