Randy Cohen, New York Times “The Ethicist” columnist, might be inclined to think so. Granted, Cohen’s anti-auto podcast from last week is about Manhattan, but several of his arguments already seem applicable to Shanghai (and, in 2020, when our city’s subway system looks like this, there will be few ethical excuses for owning personal cars in most of Shanghai). Cohen lays out five reasons why cars and Manhattanites shouldn’t mix. Here’s No. 1: “Cars kill. If you introduced a transportation system by announcing, ‘It’ll only kill 40,000 people a year,’ it’s hard to believe it would gain widespread popularity.” (The number of “traffic deaths” in China was down to 73,484 in 2008, but up 100 percent over the last 20 years.)
