That's the benefit of cycling and reasonable transit.
I'd also bet that your one-car family uses a lot less than average mileage. At least that is my experience. When I started cycling to work, a number of things we had been doing by car suddenly shifted to walking/biking... for everyone in the family.
Our mileage went down to less than 1/2 the national average... we went from about 24000 miles a year for two cars to about 7000 miles for one car. My personal mileage went to near zero, but my wife and children started doing less driving too.
