The European Commission on Monday unveiled a "single European transport area" aimed at enforcing "a profound shift in transport patterns for passengers" by 2050.
Siim Kallas, the EU transport commission, insisted that Brussels directives and new taxation of fuel would be used to force people out of their cars and onto "alternative" means of transport.
"That means no more conventionally fuelled cars in our city centres," he said. "Action will follow, legislation, real action to change behaviour."
Christopher Monckton, Ukip's transport spokesman said: "The EU must be living in an alternate reality, where they can spend trillions and ban people from their cars."
