Keen to go green? Plug-in vehicles are to be granted a range of privileges in cities across the country as part of a government plan to encourage drivers to switch to environmentally friendly cars. The initiatives are funded by the Go Ultra Low City scheme, which is backed by £40 million of public money. More than a dozen streets in Hackney, London, will develop green vehicle technology, such as street lights that can also be used for car-charging. Harrow, to the north west of the capital, also plans to create a low-emission zone offering parking and traffic priority to owners of plug-in vehicles.
