A moving vehicle is a great deal of mass that has accumulated a terrific amount of kinetic energy. When a car crashes into a wall, it transfers the kinetic energy into the wall; if the wall has a larger mass, then it is able to absorb the energy without moving. If it does not have enough mass, pieces of the wall fly off. Some of the energy turns into heat, some turns into sound (these are not significant amounts of the energy).
So, what if you could transform the kinetic energy into mass? It would take very little mass to equal the energy of a moving vehicle (I'm thinking a few atoms' worth). This is the opposite of a nuclear explosion. Instead of a force field, could there be a fusion field? Energy tranforms into some small mass (possibly even neutrinos that fly harmlessly away). Small amounts of energy would not be affected by the field (light, sound, even a walking person could pass through it) but large amounts would trigger the transformation (a bullet could not get through if fired from a gun; only if tossed by a child).
Hmmm, how to make that fusion field? Of course, there's always the Larry Niven/Frank Herbert approach: simply say it is so and to hell with the explanations. You want an indestructible spaceship made out of a single molecule? Sure, why not? How'd it get made? Who cares?
Now that I think of it, the Holtzman Field in Dune was similar to this energy-robbing fusion field. Bullets could not pass through it (nor any other fast-moving object) which is why a slow-motion swordplay developed. Fast parry, slow attack to get through the personal fields. I don't recall if it was ever explained (don't think so), but Dune is ready for another reading. I'll see what Frank said.
In the meantime, I'll think about space-time dilation. Bend the space-time universe at just that point (not with a black hole - too much bending) and the energy would have to go all the way around instead of just over the short distance it appears to the naked eye. Would rob it of most of its punch. Would do a good job of keeping the neighbors out of your yard, too. Simply walking through the field would do all kinds of nasty things to a body.
Oh boy, oh boy. I love a challenge.

I was reading in front of the Science channel a few Sundays ago, and they were airing a program on dark matter / dark energy. They think it's plausible to find and channel this in the near future. Dark energy is so mysterious at this point that folks in the know would find it intriguing and folks out of the know would dwell more on their own ignorance than that of the writer.
As for the kinetic energy problem: can the device be portable? The new polimers they're using to collect solar energy could conceivably be altered/innovated in the next few years to absorb kinetic energy for such a device - even to the point that it could assist in powering the vehicle.
There's also experimental work with EMP technology built to knock out the car's electronics. What about a satalite transmitted frequency that locks the car up?
Wonderful lot of possibilities to ponder. Thanks for the interesting topic!
