Amazing.
Some stats from 100 days in on congestion pricing:
- Complaints about car-honking are down 70%
- The Holland Tunnel has 65% fewer delays at rush hour; time to get thru it is down 48%
- 6 million fewer cars
- Half as many traffic-related injuries
- 1.5 million more visitors to BIDs year over year

How Well Is Congestion Pricing Doing? Very.
One hundred days in, honking is down; bus speeds are up.

You know what AI is decent at? Pattern recognition. So, it would be good at funding the same things that have been always been funded. That's not how we get the next cutting edge discoveries. That's not a meritocracy, that's legacy admissions.
Samuel Hammond argues that NSF should use AI to pick which proposals are funded—the NSF would only need 10% of its staff. This is not an Onion article.

The reason why EVs are such a great opportunity for a renewables-based power system (or any power system, for that matter), and why we need universal charging while parked: cars, and even heavy-duty vehicles: parked most of the time > demand flexibility through smart charging!

That's up to 10,000 minutes per year, excluding any evening or weekend trips. 170 hours — a full week. Multiplied by hundreds of thousands or millions of people.
A month into congestion pricing and my bus commute into NYC is consistently 15-20 min faster each way, no matter what time of day I travel. It has given me 40 minutes of my life back. I work in midtown and crossing the street is no longer gridlock.
It's amazing that all cities don't do this.

The point is to destroy the process. Even if in 3 months the SCOTUS decides this case, the damage is done. In a week Trump has exposed our entire legal and governmental system as a joke. We’ve been dealing on the basis of trust for the last 250 years. Just stupid.
To play this out, there will be literally dozens of lawsuits challenging what OMB is doing on the ground that it violates the Impoundment Control Act of 1974. Trump’s DOJ will argue that the Act is unconstitutional. And this will quickly get to #SCOTUS, where it will be the biggest case of the term.

The growth of global coal use has downshifted to a much slower rate, but it's still not yet peaked, according to new IEA data reported by @axios.com. www.axios.com/2024/12/18/c... Crucially growth in China has stalled, US/EU continue decline, but India & ASEAN (eg Indonesia) coal use still grows. 🔌💡
