We share the air together, you and I. It's not a matter of whose "environmentalist" or prius-driver but such reckless, redneck action should be taken into the justice systems, similar to those who intentionally modify their street vehicles into flame-throwers, etc.
coal-rollers when caught (with tempered emissions, etc. for the intentions of generating more soot during acceleration) should have their vehicles forfeited and at least another 30~50k fines imposed on them.
Ignorance is bliss me sees it and they impose their so-called "rights" on others in this case, in the name of their own "rights"...
We should have laws similar to that in Germany or Japan, where strict motor vehicle regulation and inspections are a normal part of owning, if not operating a street-legal automobile.
