If you're in the US, your gas prices are so freakin' low that you SHOULD be charged per km (sorry, per mile).

Increase the price of gas, or charge per mile.
... to see actual centre left political parties in action running countries you have to look overseas, Canada, Australia, England, etc.
Whoa, whoa, whoa. England certainly doesn't have a party with representation that is centre left, and even in Canada and Australia (NDP and Greens respectively) the parties are by no means major ones and certainly not in government. To really look for a centre left party you need to look to places like Sweden (Social Democrats, the biggest party there although not currently in power), but really, even in Europe there aren't any real centre left parties (let alone proper left wing). http://www.politicalcompass.org/euchart
The unfacts, did we have them, are too imprecisely few to warrant our certitude.
