This is one reason why I don't like living near freeways, especially near on-ramps, off-ramps, and interchanges. Car pollution isn't just tailpipe emissions - I believe a lot of airborne particulates come from tires and brakes (especially during acceleration, deceleration, and turning). https://www.cdc.gov/air/particulate_matter.html
California air quality regulators have stated that we shouldn't have any housing within 500 feet of freeways. Living near freeways increases your risk of a host of negative health effects (asthma, heart issues, etc). https://www.latimes.com/local/california/la-me-freeway-pollu...

#202I appreciate this new concern for microplastics. Since I can remember I've always had a vague fears about using plastic Tupperware and plastic bottle but wasn't sure if it was unfounded. Turns out my (and many others) intuitions were correct.
What were your intuitions? Right now the research seems to show plastic micro particles show up in a lot of places, but whether that actually causes harm remains to be seen.
I definitely think it's something that should be studied more though.

#203Didn’t I just see a post on HN that blamed ships for the plastic?

$38 billion a year in sales taxes from new and used automobiles and services. $66 billion a year in use taxes including fuel, excise, and registration. That’s just the direct revenue. If you want to include externalities, you also have to include economic activity enabled by these investments, and the taxes on those activities. Just the auto sector alone produces $60 billion of income tax revenue for state and Federa…
Road crashes cost the U.S. $230.6 billion per year, or an average of $820 per person. https://www.asirt.org/safe-travel/road-safety-facts/
There’s a difference between direct revenue & expenses and second-order effects.
As a second order effect, roads are necessary for something on the order of $10 trillion of economic activity in the US.
It’s a high price to pay to be sure, for the modern world. I look forward to self driving technology significantly reducing that number over the next 10-15 years.

>I'm not convinced trains would be viable economically like they are in Japan. In my opinion I think rail would displace a great deal of airline traffic because air travel security is such a chore, airlines have done their very best to squeeze out every last nickel and concerns about how green air travel is or is not. Add in the fact that there is far more room per passenger in a train and with dining cars (which are…
Current technologies are too far behind in speed though. Passengers will trade better wifi, food, space, etc, in exchange for longer travel times but only up to a point. If a New York to LA trip goes from 5 to 25 hours then it's no longer viable. Unfortunately the radius that trains can be competitive barely reaches from LA to SF.

This is such a tired argument and reflects your superficial comprehension of this topic. Yes, NY to LA is too far for rail service. It is the same distance from Paris to Moscow. Nobody takes trains between Paris and Moscow. However the territory between Paris and Moscow, including both Paris and Moscow, enjoy very robust rail service. The fact that the USA happens to be a large and unified political jurisdiction in n…
If you're going within a city, then home->dest time is roughly equal to home->station->train->station->dest, so if you're going to use a car anyway then you might as well just drive all the way, with more comfort, privacy, and convenience. Stations within walking distance are not realistic except in very dense urban areas like NY (which already has subways).
If you're going between cities, traffic is actually not much of an issue so it's again the same equation. Once distance increases to the point of a train being faster (even with stops), air travel then starts to become a better option.
Rail requires density. American cities are very spread out and internally sparse internally. Last mile is a serious problem, and that's before considering politics, real-estate, security and defense issues, pricing models, taxes, and other factors. Meanwhile roads are cheap and give people ultimate flexibility.
We would all love better transport, but pretending it's simple just because some other country somewhere has some trains isn't very useful.

Probably from tetraethyl lead, which wasn’t banned in common fuels until the 70’s in the US. Except in California, which had leaded fuel well into the 90's for rich people's collector cars. Another example of the do-as-I-say-not-as-I-do sorts of things that happen in California.
Yep, California banned leaded fuel for automotives in 1992, 4 years before the United States federal government followed up. https://archive.epa.gov/epa/aboutepa/epa-takes-final-step-ph...
