In railing against everything from bike lanes to transit spending, pundits and politicians often raise the spectre of a “war on cars.” Of course, there is no war on cars — but there should be. Cars directly kill and hurt more people every year than most diseases… Road injury is the eighth leading cause of death worldwide. Pollution from cars also causes acute and chronic health problems that often result in premature death — from heart disease and stroke to respiratory illness and lung cancer… Environmental impacts of cars are also well-known and wide-ranging, including climate change, smog and oily run-off from roads, not to mention the green space sacrificed for infrastructure to sell, drive, fuel and park them.
