It's as stupid as the free boxers who dump their old electronics on the street corners as it starts to piss pour rain for the winter. Who want's free toxic, useless shit?
Love the logic here. These people who slash tires are probably the same people who ride their bikes two wide, preventing me and the 7 cars behind me from getting out of second gear. Conservatively, I get 30% less mpg's at 15 mph than I do at 25 mph. You aren't helping heal the earth. You're helping to pollute it.
