> Particulates issued from tailpipes can aggravate asthma and heart disease and increase the risk of lung cancer and heart attack. Globally, they are a leading risk factor for premature death.

Minor nitpick, but tailpipes aren't the primary source of emissions. The study is about PM2.5[0]. which will chiefly be tires and brake pads. Modern gasoline engines are relatively clean, outside of CO2, though diesel engines spit out a bunch of bad stuff.

This is actually a major nitpick. If this "study" is this sloppy, what else isn't quite true?

The study doesn't mention tailpipes (afiact). This press release/article does. Don't dismiss scientists because journalists reporting their findings incorrectly.

I am a little confused, why would sloppiness in the media release (the article that uses the word tailpipe), have anything to do with sloppiness in the study, which the above comment clearly highlights is about PM2.5, not specifically tailpipe emissions?

Are Yale's media releases typically done by the people who do the study?

The study isn’t sloppy, and I would highly suggest reading it before casting aspersions at the authors:
