Watch the video of a vehicular homicide attempt, get outraged, and then commit to doing something to make your streets safer.
[Update, 3/2/2011 7:10am ET: According to O Globo, the leading newspaper in Brazil, the driver was arrested early this morning. He is rightly being charged with murder. Huge thanks to commenter victordemartino for the heads up.]
Unfortunately, sometimes, people aren't awesome. Last Friday night in Porto Alegre, Brazil, during a peaceful Critical Mass bike ride, a driver accelerated through the crowd of cyclists, sending bodies flying and injuring many. Amazingly, nobody was killed in the attack, but eight were hospitalized.
