Per several members: Some of the House Democrats who missed the Hegseth impeachment vote were on their way back from an Elect Democratic Women event at a venue about 1.5 miles down Pennsylvania Ave but got caught in a bumper-to-bumper traffic jam on Independence Ave. (the road on the House side of the Capitol complex). Some members found other ways to get back to the Capitol because their cars were effectively stopped on the road. One got out and walked. Another got dropped off on the Senate side to avoid the traffic.

Today is a BIG day for autonomous vehicles in America. DC will be taking a vote on their av bill. The bill is one vote shy of being approved by the transportation committee. Please support this legislation that’ll give the leaders of America access to av tech they’re supposed to be informed about to legislative. Action item: contact Council Member Zach Parker or Council Member to vote yes or abstain from the committee vote to keep the bill alive. Contact info: Council Member Silverman (202) 724-7772 & Council Member Parker (202) 724-8028 (main number doesn’t work so this is the communication director). Meeting starts at 4pm (3pm central)

The Federal Railroad Administration (FRA) makes it illegal to operate a train faster than 110mph, unless the route is "grade separated", ie, has no level crossings between trains and cars. This requirement was one of the big reasons California's high speed train was doomed. California has built a surprising amount of bullet-train related things. (Cynic though I am, I too would be surprised if they had managed to spend $13 billion on *literally nothing*.) However, people don't realize anything has been built because the things are, in practice, 92 overpasses which have to be finished before they can install track on them. The 110mph rule is ostensibly for safety, but in practice has negligible apparent benefits. Furthermore, instead of looking for ways to safely raise this speed limit, the FRA has instead tried to lower speed limits for otherwise-compliant infrastructure hosting Acela operations on the Northeast Corridor. My personal assessment, for what it's worth, is that if all crossings are protected by quad gates, grade crossings are *probably* safe up until at least 150mph. But ultimately, we can't really know what safe speeds are until we investigate, perhaps by crash-testing the retiring Acela trainsets. Since the FRA has expressed near-zero willingness to do so, we may never know. For a more thorough treatment of this subject, I've written about this before, here: developmentalism.substack.co…
What’s even the point of a 110mph train in Texas? The first 1964 Shinkansen had a max speed of 130mph. We can’t even propose matching the performance of other nation’s trains from 62 years ago. Loser mindset.

India, growth-wise, is where China was in approximately March 2008. I think it's fairly consensus at this point that the US was way more dovish on China than we should have been at that point. It blows my mind, therefore, that we are not thinking about India the same way.
India's poverty reduction is the second biggest in world history, just behind China's. India is now growing at around 6.5%, which is about the same as China in 2014. Manufacturing is growing right along side services. More people should pay attention. noahpinion.blog/p/india-is-q…

theme of this century's politics, i know, but *chinese* officials clearly seem to understand what's going on here and have acted decisively in a way that americans have not siiiiiiiiiiiiiiiiiiiiiiiiiiiigh

i think part of the problem is that we still over-learned from the experience of japan growing enough to mount a serious economic challenge to the US in that case, Japan didn't have any national security priorities, so once we responded the threat did just go away

Just coming in: an American Airlines Airbus A300 has crashed into a residential area of New York City. A gigantic fireball has consumed the site. Hundreds must be dead.

One thing that's underrated about New York City is that they're just an insanely bad regional actor. Doing some construction in the middle of 42nd and 9th without trying to mitigate resulting NJ traffic is one of a truly extraordinary list of examples.

I still think it's insane that congestion pricing charges the same $9 to brooklyn drivers crossing toll-free bridges as they do the lincoln tunnel drivers paying $15 at peak already

I fault them a little less for this one but it is really funny that the LIRR side of Penn Station is actually nice now, but the New Jersey Transit side is still terrible

Per a report from the Iraqi parliament, 4% of *all* household spending for the latest data is now on education *in two school grades* By comparison, Korea sits at around ~5% spread across the entire education system.
