Eeyow, I'm trying very hard not to rant about irresponsible child-bearing which contributes greatly to transportation problems and just about every evil on our planet ... OK, ok, I think I've got it under control ...
There was a time when people lived in rural areas and had to provide their own water & sewage systems, and their own transportation. I was there. We idolized cars and horsepower. We souped 'em up & tricked 'em out. Today's young people have little love for cars and many don't bother to get a license to drive. They take the bus, taxi, subway or bicycle to get around town. The trend to urbanization continues, and at a rapid rate in China and some other areas. City planners are now encouraging this to preserve what little open space remains in outlying areas.
It is ludicrous for an urban dweller to own a car today. Various services will make it more so in the future. Rentals and use of borrowed robocars will serve future urban users, but ordinary public transportation will be even more prevalent.
If you work a farm or the oil fields of North Dakota, you need your own transportation. Otherwise, be smart and use what's provided for you, often at taxpayer expense.
