    Mirrors on cars.

    I mean, logically I know why, but it just feels so weird and out of place in the 21st century.

    Like you got this high tech vehicle with a bunch of computers inside and a lot of screens/displays, radios, GPS, “assisted driving”, then you see this mirror that’s thousands of years old and not some advanced 360 radar system.

    I know that a mirror isn’t gonna fail like electronics do, so its better reliability, but still feel odd seeing old tech and new tech merged.

    I spend a fair bit of time on construction sites, and cameras have one huge issue compared to mirrors: They're one-way.

    With a mirror, I can see the driver in the mirror. I can make eyecontact and confirm that they've seen me. With a camera, I have no idea if they've seen me. Maybe they can see more, but if they happen not to be looking, I have no way to tell.

    And our stupid road regulations don't allow for both.

        A lot of production industry still runs on PLC from the 90s or older and uses DOS supervision systems. They would continue using it but are usually forced to upgrade once they run out of spare parts and / or staff that can maintain it.

        Yep, my most important tool at work is controlled by DOS software running in a 386. Plenty of Windows XP’s around too.

          I'm surprised nobody mentioned jack plugs yet. Basically unchanged since 1877 when it was invented for phone switchboards, roughly as old as safety pins or modern hairpins (give or take a few decades)

          That can't be the actual name of those, is it?

          I've always kinda wondered, and generally call them TRS or something (I'm audio engineering background, American, millennial), so looked it up:

          From https://en.m.wikipedia.org/wiki/Phone_connector_(audio) under the "other terms" section:

          The 1902 International Library of Technology simply uses jack for the female and plug for the male connector.[3] The 1989 Sound Reinforcement Handbook uses phone jack for the female and phone plug for the male connector.[4] Robert McLeish, who worked at the BBC, uses jack or jack socket for the female and jack plug for the male connector in his 2005 book Radio Production.[5] The American Society of Mechanical Engineers, as of 2007, says the more fixed electrical connector is the jack, while the less fixed connector is the plug, without regard to the gender of the connector contacts.[6] The Institute of Electrical and Electronics Engineers in 1975 also made a standard that was withdrawn in 1997.[7]

          The intended application for a phone connector has also resulted in names such as audio jack, headphone jack, stereo plug, microphone jack, aux input, etc. Among audio engineers, the connector may often simply be called a quarter-inch to distinguish it from XLR, another frequently used audio connector. These naming variations are also used for the 3.5 mm connectors, which have been called mini-phone, mini-stereo, mini jack, etc.

          RCA connectors are differently shaped, but confusingly are similarly named as phono plugs and phono jacks (or in the UK, phono sockets). 3.5 mm connectors are sometimes—counter to the connector manufacturers' nomenclature[8]—referred to as mini phonos.[9]

          Confusion also arises because phone jack and phone plug may sometimes refer to the RJ11 and various older telephone sockets and plugs that connect wired telephones to wall outlets.

            For the uninitiated, Ikarus was a Hungarian bus factory that produced buses to the Eastern block, some of those are probably still running somewhere in Mongolia. The Ikarus 256 was produced between 1974-2002, so in the best case that thing was at least 23 years old.

            But even better, someone got to travel on an Ikarus 55 on the same day (1954-1974), which used to be great in their time, but definitely weren't made for 36C summers, the lack of air conditioning combined with the sunshine roof that used to increase the feel of comfort in 1958 created a living hell for the passengers packed into that rolling museum with barely openable windows.

            Ah, so it’s the Hungarian version of the USPS Grumman LLV (Long Life Vehicle).

            The United States Postal Service needed a vendor to produce mail trucks. They ended up signing a contract with an aerospace manufacturer named Grumman. The manufacturer retooled one of their plane factories, and started producing what they called the LLV. The company sold each truck extremely cheaply, but had an exclusive maintenance agreement to service the vehicles. Their goal was to make a profit on the service instead.

            But Grumman made the vehicles too well. The LLVs were basically a thin airplane aluminum skin bolted to a pre-fabbed General Motors wheel frame, and the engines were rock solid. They skipped basically all of the modern design conveniences like AC/heating or a radio. It was basically a glorified go kart with a windshield that could do ~55MPH. It basically bankrupted Grumman, because the LLVs never needed maintenance. They spent a ton of money to retool their factory and sold a ton of LLVs basically at materials cost, then never recouped their expenses. The LLVs were produced all the way back in the 80’s and early 90’s, and the USPS is still actively trying to phase them out in favor of newer EVs. Grumman folded in the mid 90’s, after a decade of continuous losses from the LLVs.

            Basically any American old enough to vote will know what a Grumman LLV looks like, even if they don’t know what it’s called:

                  Both rely on mirrors and cameras to replace the lack of rear glass

                      Kia/Hyundai uses cameras and screens instead of mirrors in South Korea but that technology is illegal here in the US so we get mirrors. Its not too different than adaptive headlights which can adjust themselves to not blind other drivers. Legal in Europe but illegal in the US.

                      I think those are legal where I'm at, but if you have both mirrors and cameras it should be allowed by default. Also in the case of Honda e, I wonder how much power the screens and "mirrors" are eating, in a tiny car like that it might be noticeable.

                        Steam engines.

                        The vast majority of our power comes from making something really hot and boiling water. Coal plant? Oil plant? Gas plant? Nuclear fission plant? Geothermal plant? The grand holy grail of energy production that would be a nuclear fusion plant? All steam engines.

                        Yes, unbeknownst to everyone, this is what a steampunk society realistically looks like.

                            The sewing machine.
                            Like we got 3d printers than can give me whatever I want in 20 hrs but I still got to fight with a sewing machine to stitch an outfit. Like why no polyester clothes printer?

                              For one, polyester fabric and clothes are just terrible

                              Two, technically you can 3d print a chainmail shirt, but it'd suck to wear normally

                                Legally defined as secure, not actually secure.

                                They are fairly insecure in practice, since they are throwing the data at misdialed numbers and they are frequently placed in shared and insecure locations in the building where lots of people can access whatever comes through.

                                In the US they cannot be in "insecure locations" legally. And sending HIPAA materials to the wrong number is a reportable offense.

                                  Most cameras are around 5W when in use, and it looks like the Honda e has a 35.5 kWh battery, and real world testing of the Honda e comes to around 167 Wh/km or 270 Wh/mile, so if you assume 3 cameras (2 side, 1 rearview) to replace mirrors, every hour of uninterrupted driving will have the cameras reducing your range by around 90 meters?

                                      Thank you. I was mostly worried about running 5 screens at all times. Every mirror replacement system I've seen in pictures uses really bright screens and the E has 3 infotainment screens on top of that.

                                      So if we count them as 5W each (12.3 main displays are probably hungrier, but camera displays are way smaller, and they're almost certainly IPS), that's ~25W, so 150 meters by your calculation? Doesn't sound that bad tbh. And on top of that the 12.3" ones can be turned off.

                                          That's not even a government thing. It's a finance/banking thing, as most major banks are still using mainframes and legacy COBOL code for most of their business logic.
