Some of the ideas of Bikes vs. Cars have merit, but many... have a noticeable whiff of able-ism, and the film pays only minor lip service to people for whom biking everywhere always is not an option.

Copenhagen is essentially a vision of the world the filmmaker Gertten yearns for, but he negates his thesis by presenting bike traffic in the city as a public nuisance.

The film's message is certainly distressing -- there's no way humans can survive this collective auto-da-fé -- but at least the ride is fun.
