Annoying key design

One really annoying thing that seems to be growing in annoyance is the fancy key with my C30.  I don't have the keyless entry, just the "normal" key.
First, the key itself is shaped like a traditional key, but it's not similar to many of the other keys I've had recently.  My Audi key folded into itself to make it nice when it was in my pocket.  It would be much better if the thing was smaller – it's a horrible size to fit anywhere, especially into your pocket.
Second, the key itself when it's in the ignition is so close to the wiper control, and to the radio dash, that keys hanging with it on my keyring bang against things.  That's not so bad for the wiper control, but it's really not good for the radio dash – I'm afraid of wear and dents.  The other annoying thing is that the keys vibrate on the metal valet key part of the Volvo key, and that can be heard throughout the car.
I really wish they had spent more time thinking about this part of the car since it's used all of the time.  For now, I end up swinging my other keys across things so they don't bang, but they still vibrate.  I'm considering a keyring that will allow me to disconnect the car key from it, but then I'll likely lose it
