One example: on May 30, 2020 in Minneapolis, during the protests after George Floyd killing, some police were driving around the streets in an unmarked van, shooting at pedestrians at random without stopping. They later claimed they were shooting rubber bullets to “encourage” people to obey the curfew order. Of course, if you are the one being shot at in a drive by from a mystery van, you have no time to determine what kind of bullets are being fired… One pedestrian shot back! There is a video of it.

The guy was immediately arrested, miraculously without being shot to death in the process, and put on trial, but acquitted due to justifiable self-defense. The police did not drive around shooting randomly any more after that though. I see the guy even won a $1.5M lawsuit against the police now!

This is a great gotcha! I just recently learned that 700C, the “29er”, and (some) “28 inch” are all the same wheel.

To be fair, when I was little I too was guessing that “C” stands for centimeters or something metric. Now I know that “C” in “700C”, the most popular road/hybrid wheel size, stands for the third size in the French “ABCD” notation, where sizes “700A”, “700B”, and “700D” are obsolete and are no longer manufactured.

I’d love to use ISO sizes, but even if I know that I need a 40-622 wheel, there is no way to search for it on the storefront if every single seller made gross mistakes in labeling their product! I have to ignore the specs shown entirely and make educated guesses based on title alone. For example “WHEEL AL 700 FRONT ALEX AP18 QR Silver UCP” in the picture is almost certainly a 700C wheel and NOT an 18-inch wheel. The “18” in the title probably stands for 18mm rim width, which means that this wheel will fit my bike and tire, but is a bit more narrow than ideal 23mm. The sellers must be copying the title verbatim from the manufacturer, and then haphazardly filling out the specifications without knowing or understanding the actual numbers. The ISO size is not mentioned at all.

I wanted to go with this, but had to go even bigger. The largest mine truck according to the wiki is BelAZ 75710 (as seen in the picture) which has “59/80R63” tires that are merely 402.7cm big.

I think it’s precisely because there is no governing body for English and all the rules are colloquial, developed through usage, that people do get grumpy! They are the only ones who can create and enforce the rules! Each English speaker feels personally responsible and compelled to correct use they perceive is in violation of the rules the way they want them to be. If they don’t do it right then and there, no one else can.
