MINNEAPOLIS, Minnesota. When we think about the risk that cars pose to our safety and health, we often think about car accidents, distracted driving, and drunk driving. Yet, cars also pose another deadly hidden risk. According to Fortune, 40,000 people died in car accidents in 2016 alone, making 2016 the deadliest year on record in the last decade. Yet, a recent MIT study has found that these deaths may only account for a fraction of the people impacted by car usage in America. In fact, according to researchers, more people may be dying early deaths due to car air pollution than those who are dying in car accidents.
