Henry Ford did not invent the automobile or the assembly line. He did, however, change the world by using an assembly line technique to produce cars which could be afforded by everyone. From 1909 to 1927, the Ford Motor Company built more than 15 million Model T cars. Without a doubt, Henry Ford transformed the economic and social fabric of the 20th century.

3,000,000,000,000 miles per year
3 Trillion Miles
How much fuel?
At average fleet efficiency rate of 20 mpg we use 150,000,000,000 gallons of gasoline per year
150,000,000,000 gallons of gasoline per year
What is the retail cost this gasoline?
At an average cost of $2:80 per gallon
We spend $420,000,000,000 on gasoline per year
$14,300,000,000,000 Gross Domestic Product of the USA
Retail gasoline cost as a fraction of USA GDP?
3 %

VMT/capita in USA
• Peaked at 27.9 miles per day per capita in 2004• Deceased by 1.4 miles per day in 2008 – largest one year
decrease ever in absolute terms• In 1942 and 1943, VMT/capita decreased by over 20% in
consecutive years• In contrast the decrease in 2008 was only 5%• The only times VMT/capita decreased was during
i) The great depression of the 1930s, ii) World War IIiii) The Oil Crisis of the 1970s, and iv) The recession of the early 1980sv) Now

Creating Automobility
How did we go from 5 to 200 vehicles per 1000 in less that 20 years?
This change required an enormous shift in how we lived and the structure of our cities.
One battle ground in this revolution was our city streets.
Before the advent of the automobile, the users of city streets were diverse and included children at
play and pedestrians at large.
By 1930, most streets were primarily motor thoroughfares where pedestrians were condemned
as ‘jaywalkers.’
In Fighting Traffic, Peter Norton argues that to accommodate automobiles, the American city
required not only a physical change but also a social one: before the city could be reconstructed for the
sake of motorists, its streets had to be socially reconstructed as places where motorists belonged.
It was not an evolution, but a bloody and sometimes violent revolution.
