And all the while, nothing is done to get old 2-stroke mopeds of the road in Europe. It’s such a low hanging fruit to get those hyper polluters out of cities but in an individualistic society, personal cult status seems more important than common health.

These seemed like the obvious EV conversion target to me before cars for Europe. Why have these not been converted to EV?

They have, but individuals value nostalgia more than practicality.

Hiking in the hills / mountains is one of the healthiest sports there is, unless you already have messed up legs. Or other mountain sports, but at least those I do have additional risks of injury or death that most folks would find unacceptable. Not everybody has easy access to mountains, but then we all forge our paths through life and at least at certain points of life we have some wiggle room to choose where to sp…

When everyone on this planet want to live like the average European or American heat pumps and EVs won't save you from pollution

To my knowledge air quality in Europe and the US is better than in many places where people aspire to live like the average European or American.

Yes, because they're manufacturing all the shit we consume, that's my point.

Yeah it’d be cool if the phones had sensors. Everyone can see local AQI already though; weather app has AQI, and you can tap on it for a local region map, as well as a table of pollutant details.

the "local AQI" is usually from a single government sensor for 100 mile radius which is useless as pollution is highly localized (think neighbor idiots burning leaves all day) also doesn't tell you indoor air quality which where you sleep REALLY matters if the co2 is sky high best third party AQI network is PurpleAIR but even with them certain cities have few or none https://map.purpleair.com/air-quality-standards-us…

Even if measurement was perfect, people would have incentive to ignore it. Who wants to be told they can't do something, based on some claim that it might be bad for them in the very long term? People still smoke cigarettes and drink alcohol despite those being known to be bad for decades.

Air pollution, like numerous other things like water quality and medical care, is too big to be made into a individual decision.

Aside: OP are these stories just re-rigged versions of other source articles out there?

I want to pull two quotes from the article. > “Our findings emphasise that exercise remains beneficial even in polluted environments,” lead researcher Professor Po-Wen Ku said in a statement. [...] “We don’t want to discourage people from exercising outdoors,” said Co-author Professor Paola Zaninotto. The health effects of exercise outdoors are combined from two effects: - Positive effects due to exercise. These star…

Like I totally agree with encouraging exercise most places, but let’s be careful to not understate the risks of pollution. The paper states that above 35μg/m^3 of PM2.5 pollution, the protective benefits of exercise were “non-significant” against the increased risk of cancer, and they stopped measuring at 50μg/m^3. It’s reasonable to assume that above 50, it’s a net negative to exercise outdoors. There are lots of pl…

There have been days in California where just walking around outside for 15 minutes without an N95 on made me lightheaded. And that wasn’t even the worst of it with the Bladerunner skies - we all had N95s by then. Stay inside if it’s over 150 AQI.

I believe poor air quality in developing countries stems mostly from lack of technology. Cooking and heating with wood (or dung), no filters on power plants, old cars etc.

I wish more people paid attention to air quality. I'm a delivery driver and air quality has a noticeable effect on my energy levels throughout the day and also my mood. Slightly rainy days are probably my favorite days to work because no one is outside digging up roads and kicking up tire dust with leaf blowers and the rain seems to clean the air a bit.

As a motorcycle rider, it's always very noticeable. The stale air from the helmet coupled with the shit shit air from outside makes me very sleepy and you can develop a sore throat in a few hours

You might want to lookup hypercapnia clinical signs to look for. Lile sweating, increase heart rate etc. (Source: resident)

The problem is that they are not cost competitive at the time of sales and the type of people who buy those are not exactly the smartest when it comes to total cost of ownership calculation. Over time an electric version would be much cheaper (a few hundred kilometers depending on electricity price) but it's also not as convenient/capable/performant so it's a not exactly an easy sell to the target customer.

I do agree that they are highly annoying but the reality is that they are still in use because there is no real equivalency in the electric world.
