It seems that the old central-city model of urban planning works a LOT better than anything that’s come along since the invention of the automobile.
I agree that metro areas like San Diego will NEVER be able to add enough lanes to make traffic flow smoothly.
I’ve actually thought about moving back to San Francisco due to being able to get around on foot and public transportation vs driving – I find it a lot more enjoyable and less stressful. Now if they could do something about the homeless people asking you for money every 2 seconds, it would be ideal. The new mayor up there has initiated some changes in this regard but I’m not sure how much of a difference they will make.
