I believe there's a significant delta between analog and digital equipment. Given that CD players are now standard in automobiles, their ability to handle rapid, strong, and repeated accellerations and vibrations must be quite high.

Too, analog audio is far more forgiving of spurious bits of bad data. You're already doing multi-pass, buffering advanced reads, and automatically correcting for all sorts of conditions in the bitstream. If you do get a few bad bits, you're not likely to hear it, and the whole performance won't screech to a halt. Not so with data.

That said, yes the technology seems pretty robust.
