There is a very strong infrastructure of alternate transportation including feet in the Netherlands and always has been. We survived 15 years and three kids with scouting, sports, after school and school activities with 1 car that was used primarily for weekend touristing excursions or if my husband had to drive to the work site in Belgium.

My own little pontiac vibe sits in the driveways several days in a row several times a week. I am very lucky that we live where the only paces I go to on a regular basis are within a 10-12 mile radius, and that the gym is understanding and lets me bring my "bebe" inside and park it next to the reception desk instead of having to leave it chained out in the parking lot of the strip mall where the gym is located.
Marni, since you lived in the Netherlands and had the great experience of raising a family without super heavy use of cars, now living in Texas, you're a poster family of how it is possible to adapt. If the community is properly designed with transportation alternatives.
