In most urban areas motor vehicles are one of the major contributors of toxins in the air.
Polluted air can be lethal.
If one kills oneself with polluted air it is a suicide. Well, the government has not yet started charging drivers with murder or even ticketing them for their toxic contributions, but citizens have started drawing the connection. While not charging anybody with a crime, the summons points out that motor vehicles are linked to global warming, smog, super tankers and oil spills, tire dumps and tire fires, toxic surface water runoff and more. The ticket urges motorists to consider using a less-polluting means of getting around town, particularly the bicycle. These certificates thanked the recipients for their thoughtful behavior towards the quality of life in the city.
