What are the actual levels of "soot" and what size particles? How do these compare to other vehicle "clean" tech? What kind of pollution do alternative means create?

It is my opinion that "black" smoke from diesels represents large particulates that have less of a chance reaching inside lungs and more chance of falling to the ground and then biodegraded. It is easily fixed with particulate filters, which can be required. Even gasoline vehicles are being fitted with these finally in Europe. None of the research that shoves a probe up an exhaust seems to care about this.
All fair questions, but "black" diesel smoke with large visible particles (that in your opinion fall harmlessly to the ground and then "biodegrade") obviously also contains huge amounts of fine invisible particles and harmful gasses that are controlled (beyond "filtering") in newer trucks.
