It's a crazy idea, stuff like that (phones, ipods etc) should be out of the way so the driver doesn't get tempted to use them while driving. If there's somewhere specific to hold them, that's convenient to get to while you're driving, you're going to mess about with them aren't you?
troops, accept...it's a brilliant idea. You don't only need to use it for the shi5e reno has described (and i agree, rubbish like idiotPods, idiotMobiles, and other idiotThings). I battle esch day with a car park pass i slap on my facia and a 'nothing to pinch' permit from the Police, the keys to my office, a pen for writing...I think it's an idea that Volvo would love ;-) and I do, too.
