In New York City, congestion pricing leads to marked drop in pollution

> 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.

"relatively clean" means 85% of PM2.5 is from non-exhaust sources, and 15% is from exhaust after catalytic conversion. In New York EV and ICE are pretty much on par when it comes to this category of pollution, as the additional weight increases non exhaust sources.

It is different in Africa, where catalytic converters are harvested for precious metals and cars are driven without them.

That source is Europe, not New York. It claims EV's are 24% heavier than ICE vehicles. That might be true in Europe but definitely not the case in the US where the average ICE vehicle is a 6000 pound truck and the average EV is a 4000 pound Tesla.

It also assumes they're using the same tires. EV owners put on EV tires, which are formulated to have a lower rolling resistance, quieter and last longer. All 3 of those correlate with lower dust.
