I have posted a few topics discussing my negative views of the American automotive and suburban experience. I have made my views known mostly from a political point of view. I will now attempt this using economics and economics only.
If you live in one of America's large cities you may often wonder why the new highway that was just expanded or built fills up to capacity within 3 to 4 years. In some cases they are actually obsolete before they are even finished. It is because highways are considered, in economics, as close to a "free good" as you can possibly get. In economics you know that the lower something is priced the more will be bought. So consumers (motorists) are very eager to use up new lanes of traffic or new highways as soon as they are built because they believe the price of using them is so small. Say's Law states that supply creates demand. Add that to perceived price of $0 and you get highways that are doomed to fill up soon after they are built.
**Government auto subsidies equal about $5000 per auto per year. The price of highways and parking is factored into the costs of sales, income, and property taxes. So highways aren't a free good, though they are percieved to be free because you don't actually pay to drive on them. Indirectly everyone pays for them. Even those who do not use them. $5000 per auto per year adds to a large sum of money that could be used for something else that provides a better return such as mass transit rail.
