I used to work at a garage, and while an impact wrench can be the fastest way to put a tire back on a car, I eventually banned it entirely.

Everyone's lazy or overwhelmed at some point, and it made mistakes too easy to make (the problem is that it overtightens the lug nuts because the ease of use removes the proper physical feedback).

In situations where you don't have the bandwidth to perfectly educate everyone and enforce rules, sometimes it's easier to limit the toolset. A tire iron can be misused too, but it's a little harder.

On this note: I’m sad ruby style guides generally ban “and” and “or”.

   raise(“a long error string”) unless valid

This reads much worse, when the string pushes the line near max width, than:

    valid or raise(“..

Of course it’s another idiom to learn but it’s not a difficult one when used simply.
