Our first user-generated slide show, on bike traffic, was a lot of fun. (See it here.) This time out, we’re looking for pictures that show cars — the most inefficient form of transportation — hogging public space.

Reader Evan Goldin has already sent along a few, including the image at right, which he snapped with his iPhone at the 22nd Street Caltrain Station in San Francisco. He says it’s a common situation for the commuters leaving the station to be forced into a tiny space by cars parked so that they take up half the sidewalk.

You see this stuff all the time, right? People and bikes being pushed aside by cars? Take some pictures of it. Send them to sarah [at] streetsblog [dot] org. Or tag them "streetsblog" and "spacehog" in Flickr. We’ll make another cool slide show.

So far almost all our submissions are from the coastal states. Let’s change that. We want to see what you’re seeing in the South, the Midwest, the Southwest. Everywhere. Outside the U.S. is good, too.

Get your entries in by the end of the day Friday, and we’ll get the results up next week. We can’t do it without you.
