"Track home," is a mondegreen. The correct term is, "tract home."
This subject is immensely difficult for people outside the US and Canada to grasp as their situation is nothing like ours. The endless housing estates of Surrey and the other home counties resemble what we have save that the space is just so much grander. Single family houses on 3-acre lots are the norm or, in older suburbs, a quarter acre. The mass transit in the US is abysmal just because the distances cost so much to span. We must rely on cars.
To get to mass transit I have to drive 2 miles on a road with two ditches on each side, no median, and no sidewalk. I couldn't walk to the bus station even if I wanted to because of the sheer danger of walking on the road. That bus will only take me to the City of New York, not anywhere else. If I want to travel within my county, or even downtown, I must drive. To get to the train, I must drive 13 miles over two twisty mountain roads and I only live within 50 miles of New York.
Understand this. New York is one of the few places in the entire United States where the mass transit is so good that one not need own a car but only if you actually live within the boroughs of New York. A few other old eastern cities like Boston can claim the same thing, but the rest of the country was designed after the rise of the automobile and the cities are designed entirely to accommodate automobiles, not pedestrians, horses, or anything else. Phoenix and Los Angeles are notorious examples of cities designed not only with automobiles in mind, but suburbs as well. Whole downtowns are devoted entirely to commercial or industrial zoning with the assumption that residences will be outside of the city.
I find the suburbs vapid as they practically beg kids to turn to drugs or other socially-unacceptable means of recreation. The society is grotesque in that it's nonexistant. Here in my town, an exurb of New York, people arise at 4:30 to get a bus to get them to their office by 9am. They leave their office at 5:00pm to arrive home by 8pm. These commuters are so exhausted they have no time for their kids nor their community.
If the futurists are correct then the suburbs will become the next ghettos of the post-industrial era. As cities increase in population the poor will be pushed out of the city center. This is already happening in New York. Manhattan is becoming increasingly gentrified to the point that Hell's Kitchen, the Lower East Side, and Harlem are respectable places to life. 20 years ago you'd never, ever, want to set foot in these places yet here it is. The poor who previously occupied this now prime real estate are being pushed to the outer boroughs. Urban population increases as the general standard of living falls because the highest wages are to be earned in the urban centers.
I know so many people who were actually born and raised in the city and loved it yet I hear many young couples state that they want their kids to have a yard and a dog and be far away from crime and drugs. It's ridiculous. There are as many drugs here as there are in the city and now the big gangs are arriving here as well. When I was growing-up this was a sleepy farm town with 1/8 the population that's here now so this is all a bit of a shock to me.
I would love to move to New York if I could but it's horrendously expensive. If I have kids (thank God I'm male) then I'd like to raise them in the city. The suburbs are dying in the US though they don't know it yet.
Clue: The very first gated community in the United States is right near where I live. It's Tuxedo Park, home of the semi-formal evening suit known as.... the tuxedo! Tuxedo is full of extraordinary Gilded Age houses on a scale unknown even today. One house has something over 300 rooms though the owners aren't sure! The village is its own incorporated village with a private school, and a real police force who can legally arrest you. No rent-a-cops here! The country club is one of the very few places in the United States where one can play court tennis or racquets. It's very old, very old money, and quite lovely. None of the houses look the same, none of the roads are marked, and the security is very tight. All other gated communities are mere parodies of Tuxedo Park.
Fuck suburbs. They're relics of a post-war Utopian vision of social engineering whose time has long since passed.
