The Cops in Bike Lanes tumblr is just what you'd expect: photos from around America of police cars illegally stopped in bike lanes, a practice that forces cyclists to abruptly and dangerously enter the stream of automotive traffic.
The photos are often annotated by their submitters; the commentary on the photo above notes that "There is clearly plenty of room for this van to parallel park and not obstruct the bike lane if the officer gave half a second’s thought to cyclists' safety."
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
