    Why Is It That... Lord Voldemort didn't just hire a muggle hitman to shoot down young Harry Potter in the street.

    Why Is It That... In American football, tackle is an offensive position even though most tackling is done by the defense?

    Why is it That... Superman doesn't get a gun? He swore never to use his super powers to kill, but if he had a gun then his next encounter with Lex Luthor would be his last.

    Why is it That... States are divided into counties when we have no counts to run them?

    Is it because we are all countees? I never thought about that before but i do get counted from time to time, but does that count? Does a count count? I shall worry about that all day until something more pressing comes along. You can count on that.

    When we realize that patterns don't exist in the universe, they are a template that we hold to the universe to make sense of it, it all makes a lot more sense.

    Why is it That... When the motor of a vehicle is applying the drive that moves it, the person just steering it is called the driver?

    Why is it That... I never see some metric system prefixes being used? Decimeter, Decameter, and Hectometer seem to be ignored. A 4 Decameter tall building is always described as being 40 meters tall.

    Well, "40 meters" is shorter than "4 decameters", whether you're writing it or saying it out loud.

    Plus, relatively few people know what the prefixes "deci", "deca", and "hecto" mean, which makes their non-usage somewhat self-reinforcing.

    Depends on the context. Some are used regularly, others rarely. For example, automotive torques are/were often stated in daNm instead of Nm. Which would be fine by me, if there weren't also quite some low values and then you get a rather ridiculous "0.9 daNm" which simply is 9 Nm.

    Hectoliter is used a lot for big quantities of beer or wine.

    For distances, a lot of use is made of kilo, centi, milli, micro. And for some SI area units, hecto is used: hectare = 100 are. Careful: an are is not the same as an acre.

    Deci is used a lot in cooking: deciliter.

    Other prefixes are indeed rarely used. Mathematically correct as they may be, people also like to use a measurement which they have a feeling for. And then you get a snowball effect: if "decameter" is rarely used, people don't have a feel for it and so it will get used even less.
