This has probably been discussed elsewhere, but is going car-free part of a move to a more simple lifestyle? For me, the answer is a definite yes. Over the past 10 years or so, I've been working to eliminate unnecessary elements from my life: cars, unhealthy food, clothes I don't wear anymore - basically anything extravagant or unnecessary. Unfortunately, I still watch TV, but hopefully I'll be able to beat that demon eventually.
It seems to me that most **** sapiens haven't learned an important principle of evolution: the simpler an organism is, the more adaptable it is. The perfect example of this is insects, especially cockroaches. These animals have survived for about 2.5 billion years because they are simple and highly adaptable. They consumer comparatively view resources, can subsist and almost anything, and can adapt to any climate except extreme cold.
Now I'm not saying we should become like insects - we can't. But we should learn from their success. Simpler is usually better.
