As long as you're worshipping meaningless statistics, why don't you compare the two based on GDP of the respective nations? Seems to me that is as relevant as any sort of per capita comparison. China is "growing" in many ways to catch up with the US, but they aren't nearly close in terms of personal cars. That doesn't mean they won't catch up... and despite the huge gap in productivity and standard of living, their home grown pollution problems appear to be much worse than ours. Explain please?
Is oil use now a sin unto itself?
