I don't agree about the way you assess value, and I don't think it's so much about fashion as you pretend.
Mobility choices are lifestyle choices. Buying a bicycle means getting rid of parking issue and exercising everyday by default, without the cost of having to decide to do it. Despite road violence coming from car drivers, it's less stressful because it keeps you connected to your environment. The value of a bike compared to a car is like the value of a lower paying job that has less pressure, in a lower cost of living area, a shorter commute, and better offices and colleagues. You can't compare them easily.
