Weird Economic Constant Discovered

I find this graph wierd, it reveals a correlation between the miles driven in the US and our GDP. It is a constant! $3.37 of GDP per mile driven. How can it be that this number has remained a constant? The fleet gets more efficient, no effect. The fleet gets less efficient, no effect. The internet, no effect. Productivity explodes, no effect.  Price of gas?  No effect.  It’s just plan weird.

I got a flat tire once while traveling and the guy from AAA who came to fix it was a wealth of information about the health of the economy. He felt his business was great indicator. Apparently so. It implies that such a huge portion of the American economy is intimately tied up in complementary relationships with the automobile that everything that isn’t, health care for example, is just noise in the GDP.
