Half the trouble is cars and other vehicles are much wider than they used to be, most many roads are narrower what with yellow lines, bus and taxi lanes, wide parking lanes, cyclists don't have much chance on the roads these days. Many big cars and 4+4's are horribly fat and bulbous monsters. Buses are now about a 1/3 fatter than they used to be. Obesity has much to do with it. Years ago a family would go on camping holidays in a wee Austin mini, little roof rack with tent on top, boot with a primus stove, pots pans, kettle and grub and a few clothes in it.
