Japan vs The Mideast: what affects American car-buyers the most?

Looks like most Japanese auto makers are spinning up their parts and assembly factories this week or next.  Toyota to start shipping parts to auto assemblers in U.S. next Monday, according to Automotive News.  That's going to come in handy, I think, because as soon as gas gets above $4.00 per gallon, there aren't going to be enough Ford Focuses (Foci?) and Fiestas to go around.  The problems in Japan are compelling news, but the turmoil in the Mideast... and its knock-on effects on fuel price are the more compelling story for the car and transport industry.  The good news in this?  If you're hauling for Hyundai or Kia, you'll probably be getting some overtime this year!
