Not the resonance that I drive anywhere in a $40k SUV, because I don't, but the comparison in costs.
For those of us who commute regularly by bicycle, we have minimal maintenance costs, but they do occasionally pop up. Tires, tubes (I direct you to a recent rant), lube, chains, cables etc.. do wear out or break, and need replacing.
When that would happen, I would feel a pang of guilt and anxiety about needing to spend money on my bicycle to replace whatever needed replacing. But if the car needed an oil change, new tires, engine work, or more frequently, gas, there would be less guilt and anxiety because we of course need the car to get around!
I don't know why I had the disconnect in thinking that my maintenance costs and repairs were superfluous, but for the car they were not. Yes, my commute could be done by a car, but that would increase maintenance costs for the car, and other intangible costs, such as pollution and my waistline.
