I believe traffic lights currently use three bulbs, red, yellow and green. Even without color a computer system can easily determine when each light is lit.

If there are single bulbs displaying red, green and yellow please give clear examples.


Have you driven in America? We have the craziest lights you've ever seen. And that's just in my state

Flashing lights over rural intersections often do that. There is only one color there (yellow or red), but position is not a signal

How about turn signal vs brake lights?

Potentially as extraneous as range to a surface that a camera can’t tell apart from background.

More to the point, everyone but Tesla is doing cameras plus Lidar. It’s increasingly looking like the correct bet.


> doing cameras plus Lidar

At what proportion? Is it mostly lidar or mostly cameras? Or 50/50?

> Potentially as extraneous as range to a surface that a camera can’t tell apart from background.

I guess yeah for backside of the car you'd probably better off measuring actual actions.

How about when you come 4 way stop. LIDAR is useless as it wouldn't recognize anyones turn signals.


The grandparent mentioned "world wide mesh network internet". Is Amazon Sidewalk world wide? The link you posted only mentioned it launched in the United States in 2021. https://www.aboutamazon.com/news/devices/everything-you-need... shows a coverage map with large areas unserviced.

It may not be an issue for you at the moment, but outright dismissal will not keep you safe.


I work in this space and have for quite a while. There is no productized gait analysis software available to the commercial markets.

Surely archived footage would be ripe for automated analysis once the tools are commercialized.

Yes, in the same way stored passwords of today may eventually be broken by the quantum computing tools of tomorrow.

The post I replied to implied that gait analysis is a viable alternative option. Gait analysis is not an option today, or this year, or even in the next decade. There is no data supporting the claim that it can be done reliably enough to get down to practical reidentification use cases.


To add to the comparisons. Protonmail is showing as 180 MB on GrapheneOS. Add in user data and cache and it's 495 MB. I don't consider myself a big email user so I am a bit appalled.

Pixel OS16 with fastmail is 20MB for app, 60 for usercache and 7 for cache. I use it once or twice a week if that

Of course not. There might be a social media article but nothing verifiable.

I do not understand the attraction or rather the glorification of going to a Cafe alone.

"It was pure delight. Every element. Or rather, the non-existence of any element. No phone. No headphones. No tablet. No laptop." I believe I can do this anywhere.

They talk about interactions with people in the cafe but it is primarily avoiding interactions.


Byd Auto Motor, Inc. 1800 S Figueroa St, Los Angeles, CA 90015 https://www.byd.international/city/los-angeles

Ok, but "where the rubber meets the road", I've seen 0 BYDs in the wild in the US, including a recent 1,800 mile trip half way across the country. Earlier in 2025 I took a trip to Scotland and they had 2 dealerships I saw and I saw a couple of them on the roads.

Leasing a building and having an english section on the website doesn't mean they're available here yet.

The pricing page shows none available in the USA:

I don’t know how, but there are BYD city buses in Miami.

BYD makes buses in SoCal.

regarding: "Meanwhile they are dumping thousands of cars in public parking lots" Sure you can post a speculative article, but this link is far more informative. https://www.carsguide.com.au/car-news/byd-car-park-mystery-s...

It doesn't really appear to be anything of grand significance.


Gist of the article. China is a hero for ushering in affordable renewable energy. USA is the tired backward proponent of fossil fuels.

This is an area ripe for change. Politics aside, how can we make the world a better place?


> Politics aside, how can we make the world a better place?

We can't put politics aside. It's a big reason the world is the way it is.


Aside from the obvious do what you can stuff, there's a big change coming with AI so we can maybe try to see that goes well?

Politics aside, the Trump admin killed the solar tax subsidy.

plus the huge tariffs on panels. Even taking VAT into account you can get like 4x more wattage per dollar in the EU than the US

Plus they gutted the EPA and routinely go to bat for hydrocarbon fuels

I do not advise taking comedic medical advice.

Oh, it gets a lot better, I just don't want to quote the entire thing. It's very worthwhile to watch this skit in its entirety.

It's the first piece I ever read/saw of G.C., it made a lasting impression...
