Report: Electric cars linked to childhood asthma prevention

[Redaktion]

A new report shows that replacing half of all gas-powered automobiles with electric vehicles can help to minimize childhood asthma cases. The study correlated new annual asthma cases and transport emissions data from 50 US states and the District of Columbia between 2013 and 2019.

Other studies have found that with current ICE standards and heavier vehicles, EVs create more particulate matter because their batteries make them always heavier and tire wear becomes the bigger factor. So a small EV, sure, otherwise it's a wash.

Uhh, did the study stop to think that this also maybe possible due to other factors? Families with Tesla's tend to be more affluent. The neighbourhoods they come from most likely have better air quality, better access to higher quality healthcare/food/nutrition, can afford private school or home tutoring, etc.

Richer people can just live or buy properties in some gated community away from airports dumping massive pollutants on them or industrial factories. Or they don't live or come from broken homes where parents aren't bothering to vacuum and actually keep the home clean for the kids. They can afford paying regular home cleaning service. There's just lower stress levels in general.

I mean, somebody could drive a ICE SUV/Pick-up truck but like live up in the Himalaya's or Mount Everest and have access to some of the best air quality in the world, despite their vehicle being a super mega pollutant.

To summarise, I'm not exactly sure what this study is trying to show.

Not exactly. Unfortunately, to date there hasn't been a single study that looked at electric vehicles, the studies mostly took ICE vehicles, added some weight in math and made assumptions.

Unfortunately, you can't do that. Because there are other factors such as EVs tending to have more balanced center of gravity and regenerative braking. Of course as EVs move away from ICE platforms, they also get lighter in weight.

Then there is another important factor to consider, most tire/brake emissions happen on the highway when traveling at high speed which is generally away from people, even more so since PM emissions don't travel long distance or last long. In comparison, exhaust emissions is higher in cities as engines have lower efficiency at city driving and stay there longer, then there is idling. The emissions also stay longer in the air.

The study looks at areas and cars in that area over time. Rich areas or poor areas wouldn't matter for the study unless the areas which used to be poor suddenly became rich over a few years
