We recently became a one car household... I went 5 years without a car and my wife has gone over 10.

The car gets used sparingly and cost me very little aside from registration and insurance, as such I have no car payments to make. We use it for long road trips and it is also dad's taxi although our primary mode of transportation is transit, walking and cycling.

Without a car I was riding 10,000 km a year which was similar to how much I drove... driving that far would cost me about $1000.00 for fuel with my current car and current fuel prices.

The benefits of cycling have little to do with how much money one saves.
