>Trains are great

I wonder how much that sentiment is that based on steampunk and 1880's nostalgia?


Yesh go to literally any other industrialized part of the world and see how ** backwards the US is on trains

I’ve become quite radicalized on trains after visiting Japan and Switzerland myself.


OTOH, on my visits to Europe I am simultaneously impressed with the prevalence of passenger train options, but disheartened by the price. If Europe struggles to provide really affordable trains, there isn't much hope for the US. Aside from regional train options in the densest areas, we just have too much distance to cover. Infrastructure costs would kill the plan. At this point maybe we should just be trying harder to produce renewable fuels for planes.

Those are two unusually competent countries when it comes to trains. Try Germany or the UK for a more average outcome.

Not like the US didn't try. California spent 15yrs trying to build a high speed train and failed. Canada has been talking about building trains forever too and it usually goes nowhere because the budgets explode like every major infrastructure project these days.

UK spent $100M just to deal with bats in a single train tunnel, which is representative of the issue https://www.bbc.com/news/articles/c9wryxyljglo


I wonder what's different between these English speaking countries you mention failing to build out rail transit, and places like Japan and China that have built fabulous rail networks.

Bus Rapid Transit is another option that could be amazing (while being much cheaper to implement), but it falls short for the same reason as trains: they require dedicated infrastructure that complicates driving, and complicating driving is political suicide.

Also just like... looking at a train and noticing it can carry a ton more people than a car, has no concept of traffic, and can theoretically go as fast as possible.

None. Why would you think that? My guess is you're an American living nowhere near an urban rail system but I thought most people here would at least be passing familiar with modern trains. Even some American cities have them.

Why the ad hominem?

I've lived and travelled in a ton of places. Trains in low density cities are simply not working well enough. I now prefer to live in exurb and drive everywhere. It's so good.


Guessing you're American is ad hominem?

Pretty much by definition, yes.

How long does Waymo generally take to map and otherwise get ready for a new city rollout (permits, etc.)? I guess I wouldn't be surprised if they haven't even started offering rides in 2027.

No idea. I would just assume whatever they’re doing there gets shouted down in short order by the locals who are known for being kind hearted, incredibly naive, and violent.

Being slow and inconvenient would be the main reasons. Less exposure to communicable diseases and other unpleasantness are secondary reasons.

How would you know what diseases the previous passenger had?

I wonder what percentage of people in Portland are resistors. Do they outnumber the homeless?

Anyone else feel a bit queasy about citing Kahneman as a source anymore?

Point taken. But I'm not an academic and this is just hn - and I think the comment was well made.

Edit to add: The critique in the linked blog post refers to weak studies relied-on in one chapter of one general-readership book by Kahneman. I'm not aware of anyone claiming that he is generally unreliable as a scientist.


You say "just HN" but deep down it's a cabal where the rich and elite gather to laugh at the affected and groom future billionaires through advanced snobbification.

Here is a source that claims that Arizona is the #2 state for residential solar.

https://www.statista.com/statistics/1419901/us-residential-g...


Is this blog potentially suspect/misleading? Up-thread someone pointed out another source for PV production with rankings:

  1 - California
  2 - Texas
  3 - Florida
  4 - Arizona
  5 - North Carolina
  6 - Nevada
  7 - New York
https://seia.org/solar-state-by-state/

And here's a different source for residential PV:

https://www.statista.com/statistics/1419901/us-residential-g...

  1 - California
  2 - Arizona
  3 - Texas
  4 - Florida
  5 - New York
Is there any chance that people are jumping to incorrect conclusions?

£3.20/320 miles = 1p/mile

Typical ev car is .25kwh/m and at 25p/kwh it should be closer to 6p/m. Quite a bit more than 1p/m.

There will undoubtedly be a death spiral of sorts when it comes to gas stations, refineries, etc. where they become fewer and farther between as less people buy fuel. And that makes it more expensive and inconvenient, so more people buy EVs, which in turn...

Death spiral to gas stations? why? EV cars need to charge somewhere (and on long trip it can’t be at home) and people need to take a break and grab a coffee sometime too. They will change, sure, but certainly not die. Refineries will be fewer but we do need another products from them also.

Presumably a lot of people will charge at home which significantly cuts down the number of stations needed or the traffic to those stations.

For example, I have 2 gas stations within a mile of my home. They stay pretty busy because people around me constantly need to fill up. I, on the other hand, basically never visit either of those stations since I switched to an EV. I charge at home.

If everyone around me switched to EVs, those stations could not stay in business. There's a grocery store in the same area which makes anything those stations offer obsolete.

Those are the majority of gas stations that die with a mass switch over to EVs. There's a gas station for my hometown without an attached convenience store with 300 people there. There's no way that station stays in service if a significant portion of the community switches to EVs. It already struggles to be profitable as is (I know the owner).


That might be the case in places where most people live in single-family homes with dedicated garage.

Where I live (Spain) that's not the case at all - our towns are very dense. People in big cities tend to live mostly in flats (Europe's highest elevators-per-capita). Even people in the countryside, where it's more common to have a 1-family homes, often don't have a dedicated garage.


Chargers can be anywhere. They are at grocery stores, parking lots, restaurants, I can see the need for a dedicated re fuel station to disappear when charging is ubiquitous.

This is what people don’t get. Charging just means parking. The idea of dedicated charging stations where you stand around doing nothing, maybe buying a candy bar, really only make sense in the context of a fuel which is not literally already everywhere.

I've seen this on the Autobahns: what were just parking spots with unattended bathrooms are becoming little charging stations. Since I don't have an EV yet, I've not stopped at one to see how high-speed the chargers are, but at the very least, I assume that 10-15 minutes would be enough to get you somewhere more efficient/pleasant to wait for a full charge.

Charging stations will only need to be on highways if cities are sensible and build slow charging infrastructure (aka normal wall sockets) in parking spaces. Urban gas stations will be a thing of the past.

A place where you can take a break and grab a coffee is called a cafe, not a gas station.

Also, with Chinese manufacturers increasingly pushing out batteries capable of 1000+ km, you'll be able to charge fully at home for increasingly long road trips.


I'm using the definitions:

- Gas Station = retail outlet that sells and dispenses gasoline and other petroleum-based fuel products

- Charging station = place to charge your EV

Could be an interesting long bet. Will the number of retail locations selling gasoline in the UK in the year 2045 be higher or lower than in 2026?


In 2045 petrol stations will be well on the way the being about as rare as places selling paraffin or special racing car fuel today.

I don't see how this is an interesting bet. No new petrol car will have been sold for 10 years. Places selling fuel for large lorries etc will last a bit longer, but these are already a fraction of the total.


Is AVgas in a death spiral? It's survived as a niche product for a long time.

Does anyone have reliable data on the number locations selling avgas in say, the U.S. compared to the number of locations selling automobile grade gasoline?

To what extent is avgas effectively subsidized by the existence of gas cars?

How big of an operation is Tindie? Founder plus one other dev/ops/everything else guy?

the original founder/CEO left after they were acquired by Hackaday (which was separately acquired by supplyframe)

their operations have been pretty opaque since the Hackaday acquisition afaik.
