evidence: Paul Chiambaretto, who has studied the flight shame movement, cautioned that shame has its limits. "People who often travel by train are also the ones who often travel by plane," he said, adding that few are ashamed. [...] Germany — a country with a powerful car lobby, where people embrace autobahns without speed limits — spent $74 per capita on railways in 2019, compared with about $400 in Switzerland, which leads statistics in train performance. Under Germany’s current center-left government, the country may now for the first time spend more money on railways than on road construction and maintenance. (The United States spends many times more on roads than on rails.)
