I live in a city and the problems are:

1) sometimes it is noisy at night, usually because of people in cars, but sometimes because of people not in cars;

2) sometimes it takes longer than needed to walk somewhere, due to intersections

3) my house is not as big as I would like. (I think this applies to many people regardless of how big their house is.)

4) the busses are always late in winter

I know I kicked off this discussion, but I have also bemoaned many times about the anti-car people being quasi religious in their anti-worship of cars. They talk about it like missionaries talk about jesus.
