October 2005 is shaping up to be different from October 2001, when we saw a substantial rally effect in the aftermath of 9/11.

Hurricane Katrina wasn't done when she unleashed her fury on America's Gulf Coast, wiping out New Orleans and devastating other coastal areas. She also dealt a severe body blow to consumer confidence across the board.

With the effects of the Gulf Coast Hurricanes wearing off and fuel prices coming back down to more palatable levels, Americans are beginning to view their economic prospects in a more positive light.

Hybrid vehicles are gaining broader appeal among Americans. But a majority are also aware of the benefits of diesel powered vehicles, which presents a strategic conundrum for the auto industry.

This time, there has yet to be a rallying effect in the aftermath of Hurricane Katrina.

You can't have these sort of prices without a substantial effect on demand.
