Everything moves faster today :)

Seriously though we don't have the right economy to handle disruptions from oil supply problems. Everything has gone to just in time overseas production. It will unravel pretty quickly until we adjust to a older style of doing business with significant stocks of critical components. I hope and expect us to simply have serious problems with the random riot and burning slum.

In general we are in a far worse position today to deal with problems than we where even 10 years ago. I think you will be unpleasantly surprised at how fast things unravel. These last ten years of SUV's, McMansions and globalization probably increased the pain by a order of magnitude. Its like we have done everything in our power to make peak oil as painful as possible. The biggest unknown is that a lot of the people that will suffer demand destruction actually live in the same cities as the wealthy its unclear they will take dropping to a third world living standard peacefully.

Large parts of greater Los Angeles will burn for sure how this effects the rest of the US is unknown. On the east coast you have a number of the older poor cities that could potentially succumb to rioting. In the San Francisco area Oakland for example is likely to suffer riots. I think these demand destruction riots and resulting crashes in property values as people flee the effected regions will cause serious problems for the US.

I don't know Europe well enough but I'd expect Paris to have problems maybe other cities. They have good enough public transport that fuel costs are not as threatening there.

Back in the US we have a large enough concentration of poor in certain areas that depend on gasoline we are certain to have riots initiated at gas stations if they don't start for other reasons. Its hard to guess how the migration from these hot spot metropolitan areas will effect the US.
Certainly property value will plummet and business will leave the effected region the question is will it initiate a feedback mechanism causing further problems in itself. This is unknown. Near many of these poor regions is some of the most expensive property in the country so your looking at loosing a lot of wealth. America has never really had large regions that are no longer under the rule of law I'm sure we will contain the problems but at what cost ?

If your super rich and have a big house in Santa Monica I'd sell that puppy soon if you need the money. In general I'd not own anything near Compton that I could not afford to lose. Oakland I don't know well enough to guess where a riot could concentrate. Where I live in Orange County the city of Santa Anna is a potential flash enough of a concern I won't buy property in the area regardless of price. Its a double problem because its population contains a lot of illegal immigrant that work in the declining housing industry so the combo of peak oil and job loss without workers comp will make the region esp volatile. I'm sure a lot of the other poor areas in California have this same double impact situation from the collapsing housing industry and oil. Its a really bad time to have price spikes in gasoline in CA.
We have plenty of A*&Holes with Hummers in this area the chances of a Hummer being part of the cause of riots in orange county is very high.

In general worldwide riots by demanded destructed poor will be a big factor in how peak oil plays out. These riots are not the end of the world but it will fuel our downward decline. The collateral damage can easily push regions over the edge.
