Why isn't mutable a subtype of immutable, or vice versa?

As a total aside, the names `car` and `cdr` for "head" and "tail" are honestly some of the most baffling historical relics in all of computing.

  What i dont understand is why does everything have to be so brief. Take car and cdr there is only one character difference, more character differences is a good thing not bad.

    Why waste time say (write) lot (long) word when few (short) word do trick?

    Most people actually write small amounts of code in a day, saving a single character here and there typing hardly matters. Its a saving that amounts to seconds for a days work.
    More characters on the other hand prevents many potential types of mistakes, such as meaning one statement of target and actually entering another.
