Hmm interesting question, I see several things happening.
I see our current methods of transportation changing "little" in the next decade, but changing none the less. perhaps within the next 10 years well see Varible transmission tech mature (and become good!) and perhaps start to see the integration of feul cell/E85 (85% methanol, 15% petro) vehicles. maybe some more desiels as well.
The push for fuel cell tech is refreshing, but at the same time I see it as being a almost unessasairly complicated process compared to what can we done right now to improve fuel economy and minimize our dependance on oil. One of those things would be to improve battery technologies so that pure electrics become more of a option, and to convert more and more vehiciles to a ethanol/methanol blend. this would allow current infasctructure to remain the same with little modifications.
Ultimately though, running your car on hydrogen and producing H2O has a byproduct is a fairly attractive thought!
