"San Francisco isn’t in the same country as Lakeside anymore than New Orleans is in the same country as New York or Miami is in the same country as Minneapolis ... They may share certain cultural signifiers—money, a federal government, entertainment—it’s the same land, obviously—but the only things that give it the illusion of being one country are the greenback, The Tonight Show, and McDonald’s." American Gods - Neil Gaiman
No, they are more efficient at higher altitudes, mainly due to the colder intake air, but they have lower performance (as in maximum available thrust), due to the air density being lower and there being less available to burn the fuel.
Actually it's easier to manage speed and spacing in congestion with a gently curving stretch of road - cars further up are visible so you can anticipate better and slow down earlier/more gradually, reducing jerk. This way too, you won't seem slow to the people behind you. It's not so much going super slow as it is being able to correctly guess the average speed of the road and acting as a damper. This is basically what the article describes btw.
I also like to try and impose a rule of not touching the brakes unless absolutely necessary, and using 20% throttle input at most, that helps with the whole dampening thing.
One last caveat: these techniques only really work for freeways/highways in the developed world. The tragedy of the commons phenomenon is on a whole nother level in places like India or China (se asia in general) or a lot of Latin America or even sixth avenue.

I do the same. It's funny the frustration this seems to cause other people. Frustration from nothing, if they'd think about it.
"But I want to go fasterrrr! Why doesn't he goooooooo?!?!?" One time, a man and a lady in a Harley Davidson edition F150 got so mad at my for doing this that they were both screaming at me through my open sunroof, threatening to get out and physically assault me etc. They kept yelling at me to "learn how to drive". It as grid-lock traffic and we'd have minutes at a time of complete stoppage. That was a pretty awkward hour of my life.
Yeah I've had that a couple times. Once was a honk (I can only assume was) because I wasn't tailgating--yet we were moving at the same speed, so the driver swerved from behind me to the side and then in front--then slammed on their brakes.
The other time was after cruising during a lot of short stop and go intervals (so it was easy to judge crawling speed, that is to say). I eventually switched to the lane I needed and the guy who was rubberbanding behind me the entire way (pretty much going 1-10-1mph constantly instead of just sitting at 3 like me) pulled next to me and shook his head. I had a good feeling why, so I rolled down my window as we came to a stop next to each other at a light and asked if there was a problem. He said, "You drive like a dumb ass". "Oh, I do? Please tell me what I was doing wrong so I can improve". "You just drive like a dumbass". "No really, you seem like you know a lot about driving, please enlighten me". And he rolled up his window, the light turned green but he accelerated before the car in front of him had a chance to go (perhaps to get away from me, I'm 6'2" and 250lbs.), and then slammed on his brakes again...
Seems weird to me that these are still called 'ride-sharing' services. Having used blablacar, which I would consider does true ride-sharing, uber and its ilk are more in the vein of ride-hiring.
There are probably exceptions but I'm guessing that there are very few people who love their city's mass transit system if they have to use it daily at rush hour in all kinds of weather.
The video is by Ray Dalio, founder of Bridgewater, and it states that it's just his personal mental framework to understanding the economy; not claiming gospel or anything. Either way, he's kind of a big deal.
Only in the context of being physically able to assist someone else. To name an extreme, I doubt he's saying that Stephen Hawking is 'worth less' than a given able bodied person.
I think in this case the charitable reading would be to not caveat it with ceteris paribus
Let's not forget languages that aren't ideally served by qwerty - I'm thinking asian languages in particular. Even therein, there's chinese, which has a high semantic density to syllable count, vs say japanese, which requires more syllables* to say the same thing.
*more keystrokes but same time spoken, as the natural speech cadence is faster. Can't remember source right now.
Of course those Asian languages that are difficult to type are also difficult for speech to text programs, especially ones like Japanese where understanding the context is important for choosing the correct glyph.
