Every car has to have at least one design flaw that is annoying. What's yours?

What's your cars design flaw?S

Here is one design flaw on my A4, and just by the picture you notice it, the armrest hangs over the 1st cup holder, to put a cup in, you have to lift the armrest, to put the handbrake on, you have to slightly lift the armrest. The worst part is, while practicing Ju-Jutsu in my car, I broke the clasp for the armrest, so it now it catapults it's contents into the backseat whenever I want to use the other cup holder.

It's not like the wheels fall off, but it's just a kickstarter. Oh and who's idea was it to put the owners manual under the steering wheel?
