[citation][nom]husker[/nom]Although speech to text is undoubtedly safer than fumbling with a phone, why should we just assume that there is no safety hazard? Is there any evidence that it is the same as talking on a hands free phone? The assumption is that it is safe, but where is the evidence?[/citation]
Well, we could consider that when someone is texting (while driving) they sacrifice one hand and both their eyes intermittently to do it. Where as voice commanding still leaves both hands on the wheel, and both eyes on the road. That's not to say either way is not a compromise on safety, but I'd rather ride with the person who merely talking to the car, rather than a intermittently one armed blind man!
