Quality of Walking Experience
In an ideal world, we step out of our home and we go for a walk, like they did in The Last of the Summer Wine, and we socialise, and see local people. During the pandemic we could step out of the house, and go for a walk, without worrying about traffic, and without automatically taking the car.
When lockdowns ended, and the dependence on cars came back, so the local walk was degraded by the increasing frequency of car use. Eventually rural roads along secondary paths became unpleasant so new routes had to be found.
