Cars are almost without exception a complete waste of money and resources. Trust me, I run more than most, and they have a few lines all to themselves in the accounts, so I know what they cost.
To say that they're essential for people in the countryside is to ignore the fact that people did actually manage to live in the countryside when there really wasn't anything much except countryside to live in, and cars didn't even exist.
Even when cars were just starting to become popular, men and women used to walk from Amelie-les-Bains to the snow hole near my house in France, to collect snow, and to carry it, in sacks on their backs and on little trollies, back to Amelie. There they would sell it to the hotels and other establishments catering for the rich people taking the waters. It's six miles from Amelie to the snow hole, and the climb is from two hundred metres to five hundred metres, and they used to do that two or sometimes three times a day, from when the first snow fell in winter until all the snow was gone in the spring.
People whinging about needing cars in the countryside nowadays are just pussies by comparison with some of their ancestors.
