Liberals/progressives worship at the altar of public transit; why should we pollute the atmosphere with our cars, their blathering goes, when we could all just take the bus?
My guess is that a large percentage of the people who say such things live in densely populated areas (think San Francisco or New York or Tokyo). In such conditions it might very well make sense to have public transit, as it can be more economical to move large numbers of people around limited geographic areas.
But I don't want to live in rabbit hutches, stacked one on top of the other. I don't want to share a wall (or a floor, or a ceiling) with my neighbors. I don't want to live in artificial canyons. I like living in the suburbs.
But the 'burbs aren't conducive to public transit. For starters, the density of people doesn't allow for the large-scale movement of people. Places I need to go aren't all in one "downtown", either. The city folk can have their public transit, but the rest of us need our own cars.
Today I had to pick up a 1979 pickup I just purchased. It was in a shop, getting some final repairs done after sitting for years and then having a new engine installed. To get from my house to this shop in my own car would have required about 15 minutes.
But it took a little longer than that to get there via public transit. First, I had to walk a half mile (8 minutes) to get to the bus stop nearest my house; fortunately for me, the one bus that stops there was going the direction I needed. I rode the bus to the light rail station, where I bought another $2.75 ticket to take me 4 stops. A mile walk got me where I needed to go. Total time: 1 hr, 20 minutes.
As I said: public transit may make sense in dense urban areas, but not in the suburbs.
