So, after reading that studies have shown that many folks get almost 50% of their total daily pollution exposure while driving (apparently concentrations of pollutants are many times higher on the roads - logically) I'm really wanting the HEPA filter on my next Tesla. I was annoyed at $3,500 - fine. But now I can't buy the premium package without also getting the premium seats. So it's a $6,000 air filter. Okay, rant off.
