We can't "shrink the size" of people (as is frequent with microelectronics--look at transistor size, and you can explain most of the advancement)... and therefore, we can't shrink the size of cars, trucks, and roads. The computer/microelectronic field has the nice ability to change standards at any given time (think about just wireless technology and the different standards), and MOST of their advancements are nice "additions" rather than changing existing products.
That aside, I think its MOSTLY a management problem. And a "business" one. Its VERY expensive to update the highways and transportation. And you MUST do so in a way that doesn't remove the CURRENT way of doing things--you can't tear up an interstate to start a new one. And that's EXPENSIVE. And politicians (and a LOT of citizens) don't want to foot the bill for it.
As far as the IC engine, I think we're working on replacing it. But the carmakers are getting VERY good at it. The new ULEV standards are VERY low emission and very high efficiency, with a VERY good range (15 gallons of gas will get you a long way....). Plus, we have the infrastructure to deal with it (gas stations, etc). Plus, if you look at real pollution statistics, fossil fuel-fired power plants produce FAR more pollution than all the cars in America. So I don't think the IC engine is the problem. In America, at least, the "car culture" is somewhat of a problem--everyone driving all the time by themselves, the lack of feasible mass transit over most of the country, etc--that causes a LOT of congestion. And we'll need an outside force to change that--either really expensive gas (like Europe), or a conscience change over the general population (which is rare). And the former has the problem that all of our other goods would go up in price--because the vast majority of shipping in this country is done by tractor-trailer.
I don't think the leaps and bounds of microelectronics will EVER be seen in the transportation world (think about how "old" an old computer is versus how old a new car is....).... but we really do need to work on it!
