Yellow school buses at First's Wigan depot

In an attempt to make travelling to school on a bus 'cool', as opposed to having your ear bent by a parent as they drive you in the family car to school and back, yellow school buses, in imitation of the iconic US school bus, are increasingly seen on our roads. It seems a bit wasteful - the buses in regular fleet colours also do duty on regular stage carriage routes, but the yellow buses sit idle during the school day. Seems at variance with the aim of getting pupils to use school buses as an environmental measure.
