The cost of automobility

The US way of life is founded on automobility. Much of rest of the western world is also auto-dependent.

What does that cost? Arguably, the entire US foreign policy and military strategy in the Middle East since 1920 has been driven by the need to maintain security of the vast energy supplies that are needed to sustain it. Watch what happens when the Iranians block the Gulf of Hormuz. Are we about to see the start of World War 3? That is quite a price.
