Thats pretty crazy to think about.
I started driving in the mid/late 90's and I remember having a huge binder of CDs in my car, a small one on my visor and some in cases in a box in the back.
Once MP3 cd players were more popular in cars that saved a lot of room and I could fit almost my entire library on a few CDRs which was nice. I had a 6 disc changer in my old honda accord and rarely had to change any out.
Now with iPod plugins in cars CDs are almost useless. I have a single in dash CD player now, but can't tell you the last time I used it. Most of the music I listen to is through my iPhone or Sirius radio. Ive seen a few cars with hard drives which would be great to store an endless amount of media on.
My guess is in the future, you will be able to sync your car's music hard drive with your computer wirelessly. Ive looked into a few options now and they are very expensive to do so
