Why is a private toll road in Britain free of the litter that mars a nearby public road? Dalrymple has several possible answers:
Perhaps the private company that owns it takes care of it better than any British council would do. Perhaps the class of person using it is different from those who decline to use it because of its cost. Or perhaps the people who use it, having paid for the privilege of doing so, are rendered more reluctant to ruin the appearance of what they pass through.
