Driving- Necessity or Luxury?

So.. I normally stay out of political/news stories, but I read this article
NEW YORK (CNNMoney.com) -- Exxon Mobil once again reported the largest quarterly profit in U.S. history Thursday, posting net income of $11.68 billion on revenue of $138 billion in the second quarter.
That profit works out to $1,485.55 a second.
....
The big international oil companies have been criticized for plowing much of their profits back into stock buybacks and other programs to benefit shareholders, as opposed to exploring for more oil which could bring down the price of crude for everyone.
"While oil companies are earning record profits and gas prices are soaring, the largest oil companies have invested more resources in stock buybacks than U.S. production," said Congressional Democrats in a press release shortly after Exxon announced its earnings.
Other critics charge the oil companies with deliberately restricting production in an attempt to keep prices high. ......
Several bills have been introduced in Congress to enact a "windfall" profits tax on these earnings, or at the very least eliminate manufacturing tax exemption oil companies now enjoy. ....
Most plans would either use this new found tax money to fund investments in renewable energy, or give it to low income Americans struggling with high energy prices.
But so far those efforts have been blocked
Now.. at the rate of $1500 a second (that was PROFIT for Exxon) it would take less than 90 seconds to earn what my husband makes in a year. Pretty outrageous IMO. So.. the point of this poll.. My hubby & I were on our way to take him to work this morning, & the radio DJ called it un-American, Hubby disagrees, & says that it's what the "American dream" is all about, but that it sucks that they're stepping on the "little people" to make all that money. Then we got into a discussion about supply vs demand, and He believes that Driving is pure luxury & isn't necessary. Now, while I *partially* agree with him in certain circumstances, in today's society, it has become a necessity. So.. which do you think it is? Luxury, or necessary evil?
I would love nothing more than to take "alternative transportation" such as busing, however, Bozeman's busing system is still in it's initial stages, & the routes are scattered & not very often. (we also live about 2 miles outside of town, so walking to the store, various other places is out, as is Biking, since I'd be riding along the highway with a trailer carrying my 2 year old)
Alot of places have no busing at all, or it's very inadequate, so walking/biking or driving is necessary to get around. And some people with disabilities are unable to walk/bike, thus they have to drive, or be driven to get around.
Those are just my opinion(s) on why driving has become more necessity than luxury in today's society. I'd be plenty interesting in hearing arguments to the contrary, or whatever you guy's opinions are.
Oh.. best thing Hubby's said in a long time... " I really hope the price of gas keeps going up, because that is the only thing that will force our society to become less oil dependent, and make us start looking more seriously at renewable energy"
PS.. Roz, I put this in the news section due to the fact that I'm sure it will end up going OT about the price of oil & stuff.... Hope I pout it in the right place.
