Custom blinker tones to replace ringtones in popularity?

Could it happen? CNET pundit Rafe Needleman let us know via email he asked this very question after reading a Ford press release that reveals turn signals of today emit a digital tone that has been meticulously engineered by dudes in white labcoats. In the past that familiar clicking sound that accompanied those flashing green arrows was caused by a mechanical relay. With the electronic revolution having banished nearly all mechanical operations in a car besides the engine itself, it’s feasible we could be downloading custom blinker tones for our pimped rides in the very near future. 
We don’t know about you, but we’re planning on replacing our left blinker click with the THX intro and the right one with the startup sound a Mac makes. What about you?
