If people in san Francisco would really want to save gas...

The following is an idea that came to my mind while standing in traffic on the way from Target in Dally city back to San Francisco. The reason I was doing the way to Daly city is because San Francisco does not have a Target /Wall mart/Kmart or any other discount stores of that kind.
The rumour says, that the city does not allow those jumbo chain to run their business in the city. While the reason for that might be justified, the end result is that people who are trying to make a living in the city and cannot afford shopping in anything else but discount stores, find themselves driving to places outside the city. This created pollution, traffic congestion and wastes peoples time. Furthermore, I know many people in the city that will tell you that one of the main reasons they own a car in the city is to be able to go shopping in the discount stores outside the city.

I truly believe that instead of taking about how people should switch the light bulbs to annoying florescent, the city would allow more reasonably prices discount stores for the benefit of the people living in the city, we can really make a difference (and not just talk about it).
