Ethanol is not a "clean" fuel. If we use it as a transition fuel we are going to create more air pollution issues than gas. LA will become the ozone capital of the world.
Actually, the OP's usage was correct...gasoline is an inelastic good in that over observable ranges, unit increases in price produce less than a proportional decrease in demand. The demand curve for gasoline is actually a fairly interesting one, in that in functional terms, it may be indeterminate outside of relatively narrow ranges. It is certainly the case for example that relative price-elasticities vary dependent on timing. If one introduces a short-term price increase from say 300/gal to 350/gal in one great leap, demand will decrease noticably, but if one introduces the same increase over a series of narrowly separated 5-cent increments, demand will decrease by less. Some suggest that this effect motivates a pump price that is ever changing over relatively small increments such that consumers cannot become too acclimated to the actual cost of gasoline at any particular price. This type of market-segmentation by confusion would work to the advantage of oil companies by allowing them to maximize total revenue by manipulating what are in effect a calculated series of surcharges and rebates. Such a system would work entirely to the detriment of consumers and of society as a whole of course, but in a free market economy, neither of those entities actually matters for very much...
re read my post, I did not make a judgement on whether or not this person definition of elastictiy or the lack there of is correct. I simply stated the principles the person was trying to reference was indeed called elasticity versus inelasticity.
So how would you explain there being over a dozen current SUV models that have a 4 or 5 of 5 rating? Typically they are the most popular, incuding the Tahoe, Suburban, Explorer, Navigator, Pilot, and Pathfinder.
Well, in part that would be the difference between the word 'current' and the words 'to start with'. As SUV's began to gain market share, automakers needed to compete for the profit suddenly available there. Safety (of at least the supposed variety) is an easy pitch to Soccer Mom's. That said, the 4 and 5 ratings quoted are for particular crash-test results. Overall safety ratings aren't as rosy a picture. And look what happened over time to SUV prices as the result. From underselling a stripped down Chevy, they went to running into Mercedes-like ranges.

No, I don't. Like anything else, it's a mixed bag. Per the earlier, I'm happy to let the vehicle fit the tasks that it needs to accomplish. If big-time towing and hauling are on the agenda, then you can't get by with a golf cart. But for a run to the grocery store, you can.
Where I live, we have a pretty good local transit system. It only has 7 bus lines, but it covers most of the major streets in the city. It connects (via a central hub) with the train system and the LA City bus system. It also has another hub that connects the 7 bus lines. The best part is: It only costs $.25 to ride.

True enough although I don't know how many people care for the idea of using such a small vehicle to do such. While some people may live in an area where a groceary store is a few side streets away, there are tons who wouldn't want to if their journey includes a highways.
But my experiences watching parts of DC and Baltimore get gentrified and redeveloped indicate to me that it won't the middle class moving back in.
Probably a valid point with respect to expansion on Capitol Hill or directly south from Eastern Market. But there are tons of very affordable options even in Penn Quarter, and certainly on up through Logan Circle, Shaw, Columbia Heights, and Petworth. Even Fort Totten is starting to get nice if you don't mind a little gunfire now and then... :-) In SE, the projects are all slated to go, but most of the rest stays, and the new developments all include low- and moderate-income units. In SW, just about everything is going to go, but there as well, it's an all-income model that they're going by...

I see your point. That wasn't the way I read it the first time through...
