I've recently seen the movie Collapse. They make many claims about oil and an hypothetical global collapse when it runs low.
In this movie, Michael Ruppert says that a simple car tire needs 7 US gallons (~ 26 liters) of oil. He then quickly concludes that the electrical car is joke, because it needs too much oil in order to be built.
Is there any fact or study about this matter? Do we know how much oil is needed for building a tire and a car?
