I'm not sure how many of these falsehoods programmers actually believe. But one falsehood I've actually seen in the wild isn't included:
"(Direction) Street" is necessarily the same (or different) than "Street." Or even if they're different, users will understand the difference, at least on a local basis.
I had a GPS that would always omit any directions that prefixed a street name. I was occasionally thrown for a loop when it told me to turn on Beacon St in Boston, when it really meant North Beacon St, which is a nearby, but unrelated, street.
