It is true that Americans are very dependent on their cars. One reason is that the United States has a lower population density than most of Europe. On the other hand, public transportation is currently being promoted and expanded in many urban areas. Salt Lake City has a new TRAX light-rail system that has been used very heavily (by all socioeconomic classes). It was finished within budget, ahead of schedule, and it is being used more than was predicted. TRAX is very popular and many extensions are being planned. I have read that similar things are happening in other places around the country.
I personally use a bike and public transportation extensively, because it is cheaper, it is fun to bike, and it is quite adaquate for my needs. Carl
