Hey 
It has been fixed 
うちに
while
before
during
It looks like for this grammar point, none of the examples use the definition ‘before’ which is a bit confusing.
Perhaps the nuance section could give a note that うちに can only mean before when it is following the negative form of a verb as in ないうちに?

So what’s the difference between this and 最中に?
Also, why would the latter be incorrect?
Hey and long time no see!
It might not be wrong per se, 最中 is more precise since it lit. means “very middle” and expresses doing something in the middle of something. うち is more general, meaning “while”.
Cheers!
I recently encountered the before meaning. Thankfully the reading section for うちに still includes information for the before meaning. Maybe in the future it should be added back or split into a new grammar point?

The “before” meaning comes from a negative form before うち, essentially “while… is not…”. There is a grammar point for ないうちに here.

What is the difference between the two sentences? Is the 間に describing that during the whole process of driving the speaker got more and more tired, and the うちに saying that the speaker wasn’t tired, but then suddenly they were tired at some point? (Or maybe that it happened during a short period of time during the driving process, as opposed to the whole period of time?)
On of the reviews for this grammar point does not seem to match the answer that is accepted as seen below.
This is the only accepted answer and is not mentioned in the うちに grammar point.
Edit: Seems like the issue have been resolved as the review is now attached to the correct grammar point.
