Earlier quoted context omitted.
Drivers distracted by talk is already a thing through radio, phone and physical company. A purely voice-driven anki should not entail more risk than a conference call.
I'm also ethically opposed to phone conversations whilst driving, for the same reasons as above.
My country, Spain, has reached just 29 deaths per million inhabitants and year due to road accidents by focusing on the big risk factors, such as dui, speeding, lack of seatbelt use, overall disregard for traffic rules, texting and handling phones, bad infrastructure status, etc. and I don’t think talking while driving is a big part of the remaining risk factors that contribute to deaths.
That last part is just my opinion though; I’m just saying the problem is serious but imo lies elsewhere.
