BTW, your idea that there is "no strong diesel network in the US" is completely unfounded, and I'd like to know what gave you that idea. What do you think the legions of heavy trucks that drive into every corner of the US burn?
As opposed to Europe, you think that diesel is expensive and hard to find here? Diesel fuel in Europe, while much cheaper than gasoline per litre, is still more expensive than ours. One out of every three fuel stations in the US carries diesel fuel. Not bad for an apparently niche market, eh? 
bio diesel isn't anywhere near that and to have a clean fuel efficient short term solution you'd have to have a bio diesel hybrid and that would not even gain a foothold until fuel cells were ready
i'm not knocking diesels...the make good gas mileage have a higher flashpoint making them safer to store than gasoline...however they are dirtier than today's gasoline engines...make the "otto" cycle cleaner engine more efficient until fuel cells finally make it here and then breath cleaner air
