From AAA this study about distracted driving
It’s not what most of us tech savvy folks want to hear …
"Compared to the other activities studied (e.g., listening to the radio, conversing with passengers, etc.) we found that interacting with the speech-to-text system was the most cognitively distracting. This clearly suggests that the adoption of voice-based systems in the vehicle may have unintended consequences that adversely affect traffic safety."
(The OSPAN task is a complex span task that required participants to
simultaneously perform a math and memorization task)
