My fear with diesels in America is that I've been told that the method of refining petroleum over here is that it produces significantly more gas and significantly less diesel while creating about the same amount of avgas and the like. So, if consumer diesel catches on, my worry is that it will drive up the prices of doing business, as diesel is used as a more an industrial etc. fuel. So, either the cost of shipping and business is greatly increased, or the whole petroleum infrastructure is revamped in an incredibly expensive process that directly affects everybody, when they want to fill up or even for their electrical bills.
This is all predicated on me remembering the refining bit correctly, though, and I'm not sure I do.
