Sustrans , the sustainable transport charity, is running a novel variation on the “be good” day, by holding a “Change your world” week from the 29th June to the 4th July. In this case the form of “being good” is agreeing to swap a car journey for another means of transport (walking, cycling or public transport etc) or car sharing for the trip.
I spent several years working for public transport consultancies (yes, I’ve done all kinds of things you didn’t expect) and you’ll always find me on a train if its feasible, which in Norfolk isn’t too often, although I often use the train to get to London.
yours2share enables people to find partners for car shared ownership or informal car clubs.
