Edward Humes in The Atlantic:
What are the failings of cars? First and foremost, they are profligate wasters of money and fuel: More than 80 cents of every dollar spent on gasoline is squandered by the inherent inefficiencies of the modern internal combustion engine. No part of daily life wastes more energy and, by extension, more money than the modern automobile. While burning through all that fuel, cars and trucks spew toxins and particulate waste into the atmosphere that induce cancer, lung disease, and asthma. These emissions measurably decrease longevity—not by a matter of days, but years. The Massachusetts Institute of Technology calculates that 53,000 Americans die prematurely every year from vehicle pollution, losing 10 years of life on average compared to their lifespans in the absence of tailpipe emissions.
There are also the indirect environmental, health, and economic costs of extracting, transporting, and refining oil for vehicle fuels, and the immense national-security costs and risks of being dependent on oil imports for significant amounts of that fuel. As an investment, the car is a massive waste of opportunity—“the world’s most underutilized asset,” the investment firm Morgan Stanley calls it. That’s because the average car sits idle 92 percent of the time. Accounting for all costs, from fuel to insurance to depreciation, the average car owner in the U.S. pays $12,544 a year for a car that puts in a mere 14-hour workweek.
