Starting price alone doesn't give you the full picture.
After five years, Apple Watches are out of support, so even if they work their value goes to $0. The battery is gone by that time, new OSes don't support them, and their only destination is a landfill.
Mechanical watches can last decades, and hold some resell value at any age.
I've experienced this "solved problem" when visiting Germany during COVID. On every entrance to a mall there was somebody with a scanner device, and they only let you in if the scanner showed a green mark. I've been fully vaccinated (not EU) but my code didn't show a green mark on their scanner and I was promptly denied entry. The solution was to show them my German friend's code on my phone, this registered just fine, so I could enter anywhere.
So the whole "eID/CAs/ZKP/PKI" mumbo jumbo can be easily fooled by a gif file.
That part seems to qualify as an unsolved problem. But could anyone have taken the scanned data (or the GIF file) and used it to open a bank account in your friend's name? That seems like the main issue that is genuinely solved by correct implementation of this type of system.
Already today nobody can open a bank account in my name with just a picture of my passport, as the original would be required. My passport doesn't have any of the "eID/CAs/ZKP/PKI", so the question of "what exactly the addition of it solves" remains open.
My national ID card supposedly has some of it, the 17-year olds who want to pass as 18-year olds usually show a doctored gif file of their ID card, with a year of birth one or two years before the actual one; this works in ~98% of the cases.
Actually it does. Biometric passports (and IDs) have a chip which is read via NFC and the information the NFC provides is signed by a CA which is the government that issued the passport. ICAO compiles a database of public keys corresponding to each government (plus countries exchange their public keys via bilateral agreements). Unless somebody is doing purely visual inspection, any time a passport is scanned there's PKI involved to validate if the information is genuine.
Street bumps are much more efficient in lowering speed than either "automated controls" or "manual controls". You (plus neighbours, probably) could petition your council to put one (or several) on your street.
The elegant way to implement such a speed limit is to have the driver do a "slalom" between things like trees or parking spots set alternatively between the two sides of the street, or green islands in the middle of the street. It forces a low driving speed without the discomfort and potential damage caused by speed bumps.
Street bumps are a discomfort even for those who respect the speed limit, and sometimes for residents (more noise) so they don't have popular support unless it's a problematic area, with a low safety record. There are high tech bumps that incorporate a radar sped detector and instantly raise in front of speeding cars but there are costly and require more maintenance.
Yes, the idea is to provide drivers with clues as to the relevant speed. Straight roads are usually designed to prioritise motorised vehicles and often need speed limits to try to control the drivers. By designing in chicanes and narrow sections, drivers don't usually have to be told to slow down. Also, having plenty of trees makes roads a lot nicer and you may even get free road bumps from their roots.
I pass three speed bumps on my street every day. I'm driving at low speed, and the bumps are designed so to not create discomfort at these speeds. I don't even brake before them. They only create discomfort to people who drive way above the limit, which is the whole purpose, and the bumps are very effective at that.

That's a lot of "I"s for something so many other drivers in the world have to drive across, in many, many different designs. Bumps, "nipples", cushions, tables, bars, made from rubber, asphalt, cobble stone, metal, with different ratios between height and width, different profiles, etc.
But it also depends on the car, doesn't it? Some suspensions are harder, some cars are lower, this creates discomfort or damage. Sometimes they have to rev the engine to cross over at very low speed. Not to mention larger and heavier cars like vans or garbage trucks which also damage the bump on top of everything else. Sometimes even cyclists have to put their butt on the line. The Wikipedia page would have put your personal experience in context [1]. Speed bumps are the cheap for the city but there are compromises.
Many countries with well thought out traffic use bumps where safety is paramount, like raised pedestrian crossings (table). The rest of the speed limiting effect is achieved with smart road design wherever possible.
You are likely referring to prefabricated rubber speed bumps, outlawed because the material becomes very slippery when wet, endangering motorcycles, scooters, and bicycles.
Asphalt and concrete street bumps seem to be legal in 30 km/h zones.
Street bumps damage cars, make noise and create even more pollution. I head of a neighborhood action were drivers were honking on newly installed speed bumps. Until they got removed.
This could be easily solved if the EU sold tiny prepaid certificates-of-compliance that one could affix on the package itself (to show the fees were paid.) Larger weight package would incur higher fees. The post office then could stamp these certificates to prevent second use.
They could be both pulling at the strings, often in different directions with varying success. It could even be tracked by the people going in and out of favor with the admin: MTG, Carlson, Gubbard riding high? Russia's pull is stronger. Them becoming pariahs reduced to criticizing the Iran war from the peanut gallery? Israel has taken over.
My actual argument is that the theory that he's a puppet being pulled is not a serious one. Much like a chocolate for hunger, it's just an intellectually lazy explanation for people who look for intellectually lazy explanations.
±10 seconds per year would be quite an expensive quartz movement. To be that reliable anywhere it should be thermocompensated, too. This is the range of Grand Seiko 9F, Citizen Chronomaster, or Bulova Precisionist.
