The road distance of 1.536 km is about 35% longer than the 1.138 km straight-line air distance, because highways follow terrain, coastlines and existing infrastructure rather than a direct great-circle path. Aircraft can fly close to the shortest route, which is why the flight from London to Barcelona covers less ground distance than the equivalent drive.
