First thing that comes to mind is the "cupholders" on my '94 BMW 840. It's a minor gripe since I wouldn't use them much anyways, but I felt it deserved a mention here. So many things wrong, I don't know where to start.
First, they are built in to the back of the glove box lid. In order to use them, you have to have the glove box open.

So, of course the crap in the glove box goes everywhere if you attempt to use the cupholders and drive at the same time. But you don't - because there's no way the driver can drive and reach them without causing an accident, unless you have freakishly long arms. And even if you did have a passenger available to transfer the drinks back and forth, they'd end up holding them anyway since the drink will go everywhere as soon as you hit a bump. The lid doesn't have any kind of detent system to keep it in place, so it bounces everywhere if you attempt to drive with it open.
Assuming you found ways around all of this, you're still out of luck if you're drinking from anything other than a very narrow glass or a standard size drink can, because that's all that fits in them anyway.
The shittiness of the cupholders surprised me, because everything else on this car seems pretty thoughtfully designed.
I felt that mere words could not fully describe the idiocy, so I took pics.
