   Same thing happened in the seventies.  Car manufacturers did all kinds of   
   crazy things to meet the new emissions standards until they figured out   
   how to engineer closed-loop injection systems... and when they did they   
   found it was a win for performance and reliability as well as emissions.   
      
   I am betting the super-lean modes turn out to be a win in the long run   
   once the manufacturers figure out how to do things right.

   I would not be surprised to discover that is the real way to do things   
   right.  We'll find out soon enough.
