You're rapidly descending toward troll-dom,
I'll rephrase the question so you don't feel quite so righteous in evading it:

Given a choice, will you buy a PHEV truck at that time or not?

A choice?  

Many factors make up a valid choice.   Existance, cost, capability.   Just the existance does not egual a choice.   I could CHOOSE to have an airplane for transportaton, for airplanes exist.  The cost stops that choice from happening and is considered a 'non choice'.

The magical PHEVs are a non choice if the cost is too high.

The truck will probably be worn out soon, definitely within 10 years.  .......
My model recognizes the fact that some 17 million light vehicles are made in the USA each year and the average light truck is something like 6.9 years old.

I question your modelspace as the truck is 3 years old and gets 6,000 to 14,000 miles a year on it.   That and your modelspace of a 'average of 6.9 years' doesn't jive with the 20 year fleet replacement rate as cited in the past on TOD.

If he DID sell the Durango, it would probably be to someone who needs plenty of space but drives fewer miles (otherwise THAT person would buy the more-economical replacement).

Now who's avoiding?  

You keep speking of a 'lack of will'.   Yet:
Sum up the costs of feeding your guzzling truck, including the war to try to secure oil supplies, and it looks more the opposite.  How many PHEV trucks could you buy for $2 trillion?  Even if they did cost $64000 apiece and you just scrapped the ones they'd replace, you could get 31 million of them.

So you go from a free market idea (include all the costs of oil in the price) to using tax flow to buy PHEVs?

TV New Lies- And Readers of TV New Lies:

Well, I'm a veteran of the anti-war movement when Vietnam was the wizz-bang of the moral crusade against the communists, who were going to over run all of SouthEast Asia, and lots of Congressmen then were also making lots of money on the war then too.

It is not so easy to stop a war economy on the march.

None of this is new to me. And, while the time frames are likely going to be sped up, this war won't be stopped by writing letters, voting, marching in the streets, or praying either.

I've seen it all before.

I read recently, the Vietnam War wasn't ended until Congress cut off funding and Dick Nixon was forced to pull out the troops because they didn't have the hardware to continue fighting. This is true, and to get to that stage then took years.

The heart of the matter is WHY did Congress cut off funding? It certainly wasn't because Dick Nixon won the WHite House on a promise to end the war in Vietnam, which he did in fact.

It happened because the anti-war movement had been radicalized to the point where bombs were going off in this country, kids were getting killed at Kent State, the universities were being sht down, and the anti war sentiment was starting to hurt enough monied interests in this country in the pocket so THEY put pressure on enough Congressmen so that they then pulled the plug on the whole dirty mess.

Vietnam was a lie too. These people in politics are born liars. You know that.

Let me tell you how much of a lie this war is now.

When John Kerry stood up at the DNC and said, "When I was a young man, I defended my country." this was the biggest lie he could have uttered all these years later. He knew full well no one in Vietnam was defending this country, any more than anyone in Iraq is defending this country.

All those soldiers are pawns in a big game that is played with real hard cash being made by the barrel full, and much of it going into the pockets of those whom the author is encouraging us to write letters to in an effort to get this thing stopped.

Believe me when I say, no matter how much can be put at the feet of Bush & Company, they're heroes inside the beltway in Washington, heroes who are making all of those Congressmen very rich right now as it is their companies or companies in which they have an interest that are supplying the materials for the war effort through government contracts.

And the Democrats are absolutely not going to stop this war as long as it is their own personal cash-cornucopia, which is what it is since they took the midterm elections by storm. They have a mandate. And as far as they're concerned, that mandate is to get a bigger piece of the war profiteering pie.

You keep speaking of political will, yet the above and documents like from the CFR do a far better job of addressing reality than a handwave 'its all solveable 'cept for the will to do it'.   Reality has things like this:

all individual income tax revenues are gone before one nickel is spent on the services which taxpayers expect from their government.

'Influence' of markets by the govenment requires a cash flow.  Is this influence just going to be "willed" into existance?    Where is the cash flow going to come from in a world built on way underpriced energy?
