  • It has nothing to do with disliking learning. Trying to learn and use a system of measurement without being immersed in it is really hard. For years, I’ve set all my temperature measurements on my phone and thermometers to Celsius, but because I’m surrounded by people and systems that don’t use metric, I have to convert back and forth between the two. It’s a lot of mental effort for basically no gain.

    Every day, customary speed and distance units and my intuitive understanding of them are reinforced when driving and seeing street signs. I know how long a kilometer is, but if you say “My brother lives 45 kilometers away”, I’d have a difficult time truly understanding that. I wouldn’t be able to estimate how long it would take to drive there, for example.

    Another issue is cost. In my job, it would take weeks or months to update all of the documentation and code to metric. Then customers would have to approve of all those changes. A whole bunch of machinery still uses customary units too, so they would have to be replaced or updated.

    I say all of this as a metric lover and evangelist. It’s not trivial to convert an entire massive country to metric. Countries that have converted already should be hugely proud of themselves for accomplishing a difficult task.

    For the most part, I agree. LEDs are not the problem. The problem is either moronic drivers, or poor implementation of LED lights. As a driver of a very low car, the vast majority of my complaints about bright lights boils down to lifted trucks with ridiculous light bars, LEDs bulbs in halogen housings, or dufoids driving with their highbeams on. It doesn’t matter if the highbeams are halogen or LED, they’re both blinding.

    That being said, there are cars with LED headlights that are blinding from the factory:

    • 2023+ Subaru Outback.
    • Jeep Wrangler/Gladiator (compounded by having a factory or aftermarket lift)
    • Hyundai Palisade

    Then there are the cars that are designed by morons that have all instruments in the center console. That makes it harder for drivers to see when their LED highbeams are on:

    • Toyota Prius
    • Tesla Model 3/Y

    But there are plenty of cars with LED headlights that I don’t have any issues with. In my experience, Mercedes and Audi seem to do a particularly good job of having bright lights for the driver without blinding anyone else.

    And there are plenty of other cars with halogen headlights that are blinding from the factory too:

    • Ford F-Series trucks with quad halogen headlamps
    • Dodge trucks
    • Chevy Cruze (or some other small to midsize American sedan, I can’t tell)

    The luddites who want to strap jam jars with glowworms in them to the front of new cars are being ridiculous. Properly aimed LEDs are so much safer.

    When I got my new car with LED headlights, I couldn’t believe how much more I could see. I could see fae down the road. Retroreflectors on lane markings far beyond the reach of my beams are visible. Pedestrians running across the street against the light wearing all black (true story) are visible! Despite clear lenses, new bulbs, and being correctly aimed, the halogen lights in my old Civic barely reached 100 feet down the road. My other halogen bulbed vehicle is better, but it’s still a far cry from what I’m used to now.
