I don't see what people who aren't experiencing a problem are doing in this forum, other than Apple, of course.
The problem has been explained numerous times here. Saying you don't see a problem if you aren't experiencing it does little for those who do have the problem.
To reiterate: "Siri, open X application" for navigation, dictation, ordering food, and many other tasks once possible, now produces a black screen with a white car and statement: "Sorry i can't handle that request while you are in the car."
If you are navigating using with Google Maps or Waze or dictating with apps like Dragon, or launching Spotify and things like that, you should NOT have to pull over, turn your car OFF, open the app, etc. Further, an argument should not be made that programs like WAZE are unsafe to use when it is products like that, that warn drivers of road obstructions, alternate routes due to backup, and so forth.
Simply, to use the applications I have described, one MUST INTERACT WITH THE PHONE BY HAND (caps only for emphasis), thereby creating an UNSAFE situation, not a safer one.
