There is plenty of things we do not need. Like phones, computers, tvs, books, more than bare variety of food and drinks. More than couple of cubic meters of living space. Choosing what clothes or footwear to wear... All things we could do without...

It's far more cumbersome outside of cities because of distance/time and unreliable alternate transportation. It might as well not even be an option, if one decides to go without then they are consciously absorbing the inconvenience because it's an important ideological issue to them.

This is entirely incorrect. The small village I live in, in Scotland? The really crappy and unreliable public transport? Yep. I need a car if I want to get to the Reasonably Priced Supermarkets and transport the weekly shopping back home conveniently, for example.

Or if I need to travel to Place of Work/customer sites.

And then there's the long trips around the country when I want to embark on them.

So please. Don't tell me I don't need a car. Reality, practicality, beats ideology any day.
