Which is a completely different question to the "I'm going to own a car, what's the least awful option" question. But I think it's a point that does bear thinking about. The expense not incurred is almost always the cheapest option.

For the cost of a car where I live I could take taxis everywhere and have change. Or I can avoid bicycle repair issues by just dumping any bike that breaks and taking a taxi to buy a new one... that's still cheaper than owning a car. Once you look at the numbers it gets a bit scary that way.

My stepfather has done this too, BTW, and he's 60. He bikes or walks to work (it's 45 minutes walk each way) and their one car is used by my mother (she works about 20 minutes drive away) when it's wet or she has stuff to carry. But then, they're fit and healthy too... there is no causal correllation between that and getting regular exercise I'm sure. They think it's saved them money but I disagree - they'll probably live longer once they retire, thereby negating any short-term savings.
