I'm sure my numbers are off and that 18MPG for an average vehicle is not correct.  I could be way under, or way over.  I'd hazzard a guess that the average "poor" person drives an econo-box (unless they're riding around in a welfare-caddy!) {sorry to stereotype here, but you know someone will say something similar} and if so, they are likely getting more like 22 - 25MPG, if not much more.

I know that the average Dodge Charger driver is getting about 17MPG, worse if they have the Hemi.  The average Ford Explorer driver is getting about 17MPG in most cases.  Average Dodge mini-van driver about 21MPG if they are lucky.

You should get the idea I'm pointing towards.  There is little or no room for poor people to bitch about paying more in gasoline taxes here because you know what, they'll be paying much less than do the people driving around in the guzzlers.  The guy driving the 12 - 15MPG Chevy Suburban is going to feel it, but again, to what effect?

Lets look at the same equations with a 10MPG estimate.  Hmm, just over $60 a year in increased taxes if the gasoline tax is raised by $0.05.  Please tell me again how that would really impact someone's bottom line?

One more point to raise here -- personally, if the gasoline tax is going to be raised, I'd rather have it done NOW while the cost of a gallon of gasoline has been falling.  Gasoline has been quietly (thankfully!) falling in price over the last several weeks.  From well up over $3.20 per gallon back down to about $2.70 a gallon where I fill up at.

If the gasoline tax was magically raised over night and immediately went into effect, I'd be seeing prices right back where they had been only a week or so ago and I'd probably never know the difference on what caused the increase.

I would damned sure hope to know the difference a few years out though when there would hopefully be a flood of new road construction to repair existing roadways, build new ones, and help make sure that the roads we all drive on are able to handle the traffic we are asking them to carry.

There is absolutely nothing that says that diesel fuel has to see the same increases that gasoline does.  While it might help a little to raise taxes on diesel a bit, perhaps the raise on diesel comes through at something closer to $0.01 or $0.02 per gallon or something similar.  If that is the case, then costs to the trucking industry are still not that harsh by comparison.

Finally, your example mentions that every single consumer in the country would see increased prices.  That is true, as would also be true when goods produced in the U.S.A. are sold over-seas.  I'm well aware that the money for paying for transportation will have to come from somewhere, and that costs will be passed along, but if that is the case, then what is the real impact to the truckers?  Not that much, no?  Because they will definitely pass the costs along and force someone else to pay them.

If that really happens, then again, we are likely talking about tens of dollars per person at most.  Totals of under $100 a year in indirect costs that are passed along to the consumers.  For a family of four, the total hit -- including their own average driving costs -- would be under $500 a year.  Not an inconsequential amount, but an amount that should be manageable.  Roughly $10 per week.  10 fewer dollar deals at Mickey-D's, 2 or 3 fewer Starbucks drinks per weeks, etc.

Given a choice, would consumers really rather not pay the $10 per week to help make the roads better?  Help pay for more mass transit?  Build new roadways to help take traffic off over burden roads?

I can tell you that for me the choice would be fairly easy.  

Simple math = $500 year / 52 weeks in the year = less than $10 per week.

Would that hurt?  Perhaps, but then again the Congress just handed people at the lower end of the economy an increase in their wages, no?  And are we not already paying more, or going to be paying more for milk (as it shoots up thanks to increased transportation costs and increased costs of food for milk cows) and meats (as we again pay more for meat because the feed for beef cattle has gone up in price).

Everything goes up in price.  It has for many, many, many years.  Everything that is except for the gasoline taxes which have remained stagnant for many, many, many years.

Let's say for the sake of argument that all your figures are correct.  So what?

It is the same thing that the democrats preach in Washington - "It is only X dollars! - The cost of a pizza (or insert your own item)."  This is true.

None of these taxes (with a few exceptions) are "that big a deal". Just a couple of bucks a week, month or year.  But added up and it is a burden that would blow away most people.  And that is how politicians get away with it.  Just a nickle here, a dime there, so you do not squeal too loudly.  Until 100% of your money is taken in taxes (with of course a stipend coming back to you so you can thank the government for their generoisty).

it is not for a lack of money that roads and bridges are falling down.  It is for a lack of accountability and competance that they are.  And I do not want a nother nickle or dime to go to them, until they stop wasting the trillions they are getting on pork and other feather bedding, and start using it for what our government was designed to do.

With the age of technology, everything has gotten cheaper as we have used technology to build it cheaper and faster.  Everything that is except Government - which is defying the law of technology and of the trends of society as a whole.  That is not an exception to the rule, that is just fraud and waste.

And I for one am not going to vote to give them more money to waste or line their pockets with. period.

Then lets make it dollar for dollar.  If they want to raise taxes on gas, cut it some where else.  In the end it is all just an accounting gimmick anyway.  All the money goes into the same pot and it is only politicians that say "this is for x".  In the end, it all comes from the same place.  Our pockets.

No new taxes until they eliminate or reduce existing taxes.

What kind of driving are you doing?  Short haul?  Speeds?

A friend had one of the big Chevy SUVs which had the little dashboard computer display that showed time/temp/fuel mileage/distance travelled type stuff.  It was painful to sit in the passenger seat seeing the fuel mileage (efficiency or lack there of) displayed.  I think it topped at an estimate of 15MPG when he was driving through the parking lot, and went down to the 12MPG range when he got out on the roads on our work campus doing the posted 25MPH limit.

The Explorer I drove for a while got me about 17 - 19MPG when I was using it, and actually darned close to 20MPG when I took the whole family down to Orlando on a Disney bound vacation.  For that trip I made heavy use of the cruise control and tried to keep my speed somewhat reasonable so I could avoid having to pay any entry/exit fees in the form of traffic citations along the way.
