Wait, but airport scanners HAVE reached this type of analysis level—the only problem is that do so the x-ray emitter has to rotate around the bag (or the car in this instance) to create a 3D model of the objects within, which is then used to estimate density to a high degree—and from there things became much easier.
Of course, they’re used to analyze bags, not cars, and the objects have to pass within...but still
A 3D density map does not reveal the chemical structure of the material in the interior. You’re describing abilities of X-ray scanning consistent with Constantin’s description, which fall far short of a “tricorder” or detecting fentanyl inside a car. Looking it up airport scanners can also use millimeter-wave scanning, which I believe still fits Constantin’s high-level description of scanning methods in the high-penetration/low-detail side of the tradeoff.
A 3D density map does not reveal the chemical structure by itself.
Since you also have the X-ray spectrogram of the material, you can narrow down the materials that have the same spectrogram but different densities—i.e. organic compounds and water
