It all depends on where it goes off.

I have been looking for confirmation of this story but have not found any yet. Which means very little as I do not regard my searching abilities as any great shakes.

This site has also issued warnings. Some think it also a dubious site, but they have been correct on several attacks. For what its' worth:

AQ have not done car bombings here for one reason: they know that once shopping malls filled with teenagers or elementary schools start exploding, the soccer moms will in short order support...no, demand either mass deportations of all middle-eastern types. This would basically shut down AQ's ability to function in the US with the level of freedom that they have become accustomed to.

AQ won't do car bombings here unless it is part of a grand finale, and something tells me that will either be biological and/or nuclear.
