This was not intended as a joke or as a pseudo-The Onion article. If pollution cannot be mitigated at the source (for whatever reason), and that pollution is causing problems, and those affected have a way to take action or are required to take action...things will probably be tried*. (The tunnel approach may be useful...enclose all roads or move them underground and then filter all air in them.)
* the dispute with California continues. The latest is the EPA is telling California that the homeless population there is resulting in Clean Water Act violations (yet fracking is okay?). Also, a few days before that California was called out for not meeting air quality standards, just after being told it can't regulate emissions... https://www.cnn.com/2019/09/24/politics/california-trump-epa-threat/index.html Tesla has already demonstrated that their HEPA filter carrying cars (most 2016 and newer S/X) can function as air scrubbers for PM2.5 pollution, cleaning both the cabin air and surrounding air (at least until the filter is clogged). See link for test. (BTW, PM2.5 exposure levels can also be translated into a "cigarettes smoked per day" equivalent health risk. 22 ug/m^3 = 1 cig per day. On the Air Quality Index scale, 22 ug/m^3 of PM2.5 is AQI 71 or 'Moderate'. Los Angeles average 24 hr air quality is the equivalent of about 1/2 of a cigarette per day, per person. EVs do reduce but not eliminate local PM2.5 emissions...tires are still a source, as are brakes, when regen isn't enough by itself.) There are also parallels elsewhere. City-scale water filtration systems are being added in communities across the country to deal with water pollution problems that our society has created for ourselves by not stopping pollution at the source. Now instead of sourcing water from pristine lakes, rivers, and aquifers, advanced filtration is necessary. Some cities are actively trying to protect their water sources to avoid needing to go down the route of costly extra filtration later.
