In Motoring is triple threat to bicycling and the environment, I showed pictures of how motorists and their steel boxes destroy street infrastructure, including trees and bike racks. I asked for reader submissions.

Lee of Car Free Chicago sent in these two photos of a traffic collision at Sheffield and Belmont in the Lakeview neighborhood of Chicago, Illinois:

Tree cracked and knocked over by motorist.

Richard of Cyclelicious linked me to two photos he took showing the damages motorists cause:

City crews are out to replace a damaged stop sign in Colorado.

The motorist who caused the downed power lines seen in this photo unfortunately suffered a heart attack while driving in California.
