I hope the article didn't
I hope the article didn't make it seem all taxes collected on gasoline went to road maintenance. That would be ludicrous, especially in California where our roads, at least in and around cities are in deplorable state. Yes, mass transit and transportation is part of the tax. Thanks for the clarification.
On another note, I tried one day to calculate a commuter diesel locomotive's MPG and the train conductor laughed and said he never thought of it that way. The calculate gallons per hours burned. In all fairness, it still is the best and most efficient way to transport good and humans, but that is another topic.
