Can this be useful in a car?

Along the lines of their analogy with the car engine...
People like to use stiffer engine mounts... hmmm wonder why....
Personally, I see no good in decoupling. I'd make sure that speaker was stuck as firmly to the box as possible, brace the hell out of the box and make then it heavy enough to not move at all. As Adam pointed out, you're losing output energy.
Decoupling would only be if there were constraints, such as mass or space, such that I wouldn't be able to add the weight necessary or add enough bracing for the enclosure to not move along with the speaker.

The amount of energy you would lose on something like a midrange driver (where I could see de-coupling really helping) would be so minimal that I think the benefits would far outstrip the caveats...
Stiffer engine mounts have nothing to do with a comparison about the resonance of a cabinet...usually stiffer engine mounts are used in sportier cars where controlling transmitted vibration & noise is not the issue ...applying maximum & more immeadiate transfer of energy is.

The fact remains that the 'decoupling' only achieves what adding mass and stiffening the box already does. It just does it at the expense of size and weight. If you can afford both of those expenses, then there's no need for any exotic decoupling materials.

^ My idea does not involve exotic materials. Everyday stuff.
And it is difficult, and not always wise, to add a ton of mass to a car door. Stiffening can be tough too so in this case the less energy you put into the enclosure (the metal skin) the better IMO.

You're wrong.
Decoupling is intended to eliminate the vibration in the enclosure walls from the speaker going through it's cycle. God himself could build an enclosure and that would still happen if he didn't decouple.
Super expensive cables aren't expensive for no reason. They use technologies to help flow power more efficiently, or, if your refering to AC power cords the're super expensive to elimiate any noise that may be induced through an amp/reciever. They may be stupidly expensive, I'm not arguing that point, but they are expensive for a reason. I supose power conditioners for home audio are just a farce too [img]graemlins/dunno.gif[/img]
