When I started bike commuting to work, I figured out that you really don't save money unless you drop a car. So to me , this is a huge step forward. The winter will be harder for sure. We don't live right down town, more like in a bedroom community that has most things within walking distance.
The cars/resident ratio is actually a pretty interesting number. I have a brother in law who is a solid 1.5. I like to bike to his place and see the disgust in his eyes.
