It's all about priorities: AVIATE, Navigate, Communicate.
Pilots and others with some level of emergency services / high stress career training know how to prioritize.

Speech-to-Text at its current level of development will absolutely make matters WORSE. Texting while driving makes drivers more stressed because of frustration: what's in my mind is not appearing on the screen and that means I have to try two or more times to get the message to show up correctly. This greatly increases my level of stress while driving, which is why I don't do it.
When I'm driving, if I feel like I am becoming stressed, I remove all distractions: the radio is turned off, the girlfriend has learned to be quiet, and I concentrate on the road. I wish everyone would behave this way.
