Should you live near one of those big noisy "freeway" things you may note the little black particles over everything in the surroundings but nobody likes to tear down the interstate.

Lots of urban areas in the US have been resisting, tearing down, and/or relocating major roads since the freeway revolts of the 1970s:

I have two things to say to that.
First, I live 150 yards from a major freeway - I-90 in WA, it's three lanes in each direction here. There are no tiny black particles over everything in surroundings, and my outdoors AQI (from my own sensor) is normally in single digits and basically only ever gets above 50 if it's wildfire smoke or the neighbors are burning something.
But second, if we developed a reliable and cheap way to, say, teleport people over long distances, why not tear it down?
Note the use of 'may'; the details of the car-hell vary. Perhaps the I-90 pollution instead spills into the lake and then bioaccumultes into larger organisms, Bon Appétit! My anecdote was a bit southwesterly of the I-5 bridge where there was, besides the horrific noise pollution, definitely a greyish black soot to clean off everything. A fine result of rolling a natural one and automatically failing the skill check for "copy the autobahn", probably.
As to why some beings need to be whisked hither and yon with such haste, and thus spend quite a bit of time (and energy) trying to be somewhere, anywhere else, well, are they hungry ghosts? Or maybe they min/maxed for wizard and ended up with only three points in wisdom?
How are you measuring your AQI, and what particle size? Tire particles aren't PM2.5 AFAIK and are very hazardous to your health.
I think the freeways are going from larger particles to smaller ones as DEF gets rid of the bigger diesel particles.
smaller stuff is more dangerous and goes deeper into your body:
- PM10: inhalable dust entering the nose and mouth.
- PM4: respirable fraction that can reach the gas-exchange region.
- PM2.5: fine particles that penetrate deep into the lungs.
- PM1: ultrafine particles with potential to translocate beyond the lungs.
