> I suspect though that it’s often a case of people noticing these type of design flaws but not having the authority to fix them while those with the authority don’t care.

Kinda related but also not really, my own pet peeve is the pouring spout in many products, coffee machine, water jugs, buckets... they might look effective but I find that more often than not, they are curved too much and drip all over when actually pouring.

And I always have to wonder, after serving coffee from one of those things, did the person who design it never even try it just once? Didn't they ever use such a thing, they never ever poured water from a pot?
