I don't think that I would use it very often, but wouldn't a virtual exhaust note GUI control on the Tesla vehicles be fun? Pick your favorite exhaust tone (ie Lamborghini, Z06, Hemi, Ferrari etc) and it would sync it with your speed and accelerator? I could have some fun picking different vehicles. Then when I was done playing and remembering a different time, I could turn it off and resume my silence. It would be a great way to bring in old school buyers! It's probably never gonna happen, but it is totally doable and would entertain me.
