This card was designed by Peter Miller as an alternative to the kicking-of-doors and yelling-and-screaming that usually goes on when someone in a car recklessly endangers the life of a cyclist because they were talking on their phone, putting on lipstick, passing another car in the bike lane, etc etc etc. It's a more subtle statement, but I think more effective. Peter has provided a PDF of the card to allow others to print it out on a magnet of their choice and distribute them as needed. [Thanks to TOLA for noticing it.]
