I have lived in Europe and I know that can be a viable option for many people. But there are many places in the US where there are no real alternatives to a car. I have lived in my house for 18 years, bought at the beginning of 2007 before the market bubble popped and haven’t been able to afford to move since then. In 18 years I have seen exactly two people riding a bike near my home and I sometimes wonder if they’re still alive.
