text: Paris bans driving due to smog by Robert Duffer, "after days of near-record pollution, Paris enforced a partial driving ban to clear the air of the global city." Because of the large amount of people constantly driving, it caused the city to become so polluted that they had to ban people's ability to drive. If people carpooled more, or took more public transportation, then this wouldn't have happened. Some delivery companies even complained of "lost revenue."
