Edit: OK got it in the article, it's driving a car too fast.
Except your car is your brain and so it's burning yourself out I guess. A little confusing
As a “petrolhead” this instantly triggered me: most cars won’t redline at 100mph, actually they won’t even break a sweat (at like 2.5krpm, when redline starts at 5-8krpm depending on engine type and model). Redlining is _accelerating_ too fast, not _driving_ (this means you cannot “redline” indefinitely long, only for short bursts, even if you are a racing or overly aggressive driver).
In the manual-driving world, you can easily redline a car even below 100km, by just not switching to a higher gear in time (to get faster accelleration)
Redlining: drive with (a car engine) at or above its rated maximum rpm.
I also think of the movie "Redline": https://www.youtube.com/watch?v=9FZ0AXNldV8
(But yes, depending on context, the word has the other meaning you note.)
I tried doing this a few times. It's hopeless. Responses to questions range from "I don't know, I was just told" to "Let me get back to you", with the occasional impression that the person being asked is thinking "Why is the worker thinking about the task instead of doing it".
I've come to the conclusion that it's easier to just do the task and leave the why of it to the people who are supposedly paid to worry about that.
I'm not quite sure I said anything closely approximating that?
