We should be advocating removal of subsidies to oil and gas companies long before we push for an increased gas tax. I suspect that if all the direct subsidies were removed, and some of the (many many many) indirect subsidies the market would be much more likely to take care of itself.

In the current political climate, this is an easier sell than making gas prices even more expensive through taxation.

Only with that log burning in the fire would I throw in the much bigger and greener increased gas tax log.
