Lots of cars now have audio jacks that can connect an iPod to the car stereo where you can control the iPod to play through the cars speakers. That's good and all but you have to bring your iPod into the car everytime you want to use it. Why hasn't there been cars yet that have large hard-drives in them where you can connect your iPod or media storage device and copy the music and movies you have in your iPod onto the car's internal hard-drive so that you always have your iPod's music in your car and don't have to worry about bringing it with you every time? I figure this technology can't be that far away and should already be existent in cars of today. You can do this with the PS3 and the Xbox 360 - why not in cars?
