In-car iPod – let’s do one properly!

Why is it everyone seems to think that to play our iPods in the car we want some stupid bit of plastic on a stalk, with wires going in to the back of the existing hi-fi, all at great installation expense? What we want is an in-car hi-fi which you can slam the iPod into, just like a cassette (or an oldschooltastic 8-track). Why does nobody make one? Yes, something like this:

Or perhaps someone does make one. If so, let me know!
