Two weeks ago, China became the first nation to operate a maglev railway commercially, when officials inaugurated a 30-kilometer-long line between downtown Shanghai and the city's airport.
You can walk from downtown Shanghai to the airport there in less time than it takes to drive by car.
The Shanghai airport is about 30km away. It is impossible to walk that distance faster than it takes to drive a car there.
