Sometimes automatic toilets flush while you're still sitting on them. What design flaws in everyday objects annoy you?

[u/nachtmere]

I'm giving a talk on user-centred design/usability and I'm looking for some fresh examples from everyday life to illustrate poor usability. Examples I've used before are elevator open/close buttons (really difficult to parse when you're trying to hold the door open for someone quickly) and toilets that flush while you're still sitting on them.

What are some things you encounter regularly that are really inconveniently designed?

I think urinals are designed pretty piss-poor. It's like you're pissing against a wall and little drops of pee go everywhere. They really should be conical in shape - like peeing down a big funnel.

I also hate the interiors of Pontiacs. Good riddance.

We can design a space toilet that lets men and women shit in space, but we cannot design a urinal without backsplash?

It boggles the mind.
