> How can you possibly say that crude is half of the pump price?

I googled for a couple sources on the breakdown of the price of gasoline, and they seemed to be in agreement that the raw cost of crude is somewhere around half. (And broke refining out separately.)

I'm sure it's not perfect, but it seems fairly reasonable. (And it can be off by quite a lot and still not make a huge difference to the cost-per-km of driving.)
