My previous car, an LS 460, had a multi-disk CD/DVD drive and an HDD. The audio system automatically converted audio CD's to MP3 files from CD to HDD. But due to concerns about copyright infringement, they placed a lot of restrictions on what could be copied (only original audio CD's - no copies - no CD's with MP3 or WMA). The car would play CDs with MP3 files - but wouldn't copy the files to the HDD.
By omitting the optical drive, Tesla has simplified their audio system (eliminated the extra complexity of having an optical drive) and also avoided the copyright issues - because if there is any copying of copyrighted material onto a BT or USB device, it's done before it gets to the car.
As more software functionality is added - would be even better if the car would be able to connect via WiFi and access content from personal media servers.
