On the other hand, it's nice to see BMW recognize that MP3 support is an important feature to sell cars, and Apple recognize that car integration is an important feature to sell iPods. Follow both of these points to their logical conclusion, and you could imagine cars shipping in a few years that are "iPod ready" and actually do something intelligent with the UI. At that point, you could even imagine third-party manufacturers being forced to support whatever protocols Apple speaks in order to be compatible with the iPod connectors.
