Do you really believe the current system of flashes was the only system used for the last 40 years? Or that the system was perfectly strict with 1980's technology? These systems were implemented city by city and were not exactly the same. Some of them even used audio or radio instead of strobes. What you describe does…

If you’re turning right, you are crossing TWO crosswalks. _| If you have the green, then the second crosswalk | has a walk signal. If you have the red, the first crosswalk _ has a walk signal. The driver turning right must always watch for pedestrians, regardless of red or green.

@Darth: That’s mostly a myth/legend these days. There used to be some lights long ago where that would work, because they had early, simple detectors for emergency lights to allow police and ambulances through on a green. But since then most cities have moved to more advanced detectors which look for more specific…

I use mine, but only because they didn’t have one without it when I bought the car.

My wife is that way, while I love the automatic lights. Makes things interesting when I borrow her car near dusk. (Why can’t I see? Oh yeah.)

We don’t need to go away from batteries, just go with LiFePO4 or another alternative instead of Lithium Ion. Some EV cars are already doing this.

Why do chargers have names? My first guess was street names where the nearest other charger stations were.

Even when done politely, the “you don’t deserve to be here” attitude still shown through.

This is only stopping it from being sold to new players. They aren’t removing it from users who already have it. (So far.)

Physicists also expected antimatter to behave similarly. They just couldn’t prove it until now. So your ignorance is not betraying you, at least not in this. Most experiments involve a few hundred atoms of anti-hydrogen, at the most, and they must often be suspended by magnetic fields to keep them from touching matter.

I doubt that will happen, for the same reason that Guinness Book has shut down entire categories of records from any future attempts.

The plan looks like fewer satellites in a slightly higher orbit. (Compared to Starlink.) So the operational lifetime could be longer.

Compared to what, plopping down thousands of new cell towers in hard to access areas? The size of the antenna actually reduces the power needed for each signal, because it can form a more narrow beam.

Still, they could have painted it black to minimize brightness. Or read a few pages of the document SpaceX published…

Seems like the Nintendo plans are the real revelation, especially in a court case about anticompetitive mergers.

It’s in low orbit. It’s very definitely going to reenter, eventually. The question is about when and where.

Yes, 10,000 is tolerable for unpressurized flight, but 8,000 is much more comfortable to the general public in day-to-day usage.

“Car suffered a low tire pressure. Driver swerved! (slowly and carefully) to the side of the road.”

Thought it was usually 7,000-8,000 ft cabin pressure. 10,000 is a bit rarified.

That can be good, but there are a variety of such systems in different cities, and they are not all compatible with each other. Another issue is that “getting out of the way” sometimes involves disobeying other traffic rules, so it’s not always clear what the best way to help is. I’ve seen human drivers block an…

Stupid drivers sometimes block emergency vehicles too.
