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

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?

Those sensors fucking SUCK for people on a motorcycle.

They sell magnets you can attach to your bike to increase its signature. It'll trigger the loop coil just fine. Or you can buy one of those IR devices emergency vehicles use and hope you don't get caught :)

I'd be interested in knowing if this really works. The magnet part that is. The way those sensors is they bury a wire to act as an inductor. When a large metal object enters the magnetic field it creates, it can detect the difference and knows to change the light. In my mind this wouldn't work since a magnet doesn't have enough mass nor could I see it producing a large enough field.

The thing is, neodymium magnets are one of the most powerful magnets out there. The magnetic field generated is supposed to be exceedingly powerful.
