> No, talking in a car has no measurable impact on safety. And talking on the phone is obviously even safer than talking to other people physically in the car, since you don't need to take your eyes off the road or tour hands off the wheel like you would be tempted to when talking to another person in the car.

Curious why you state that so confidently when every study I'm aware of has found the opposite.
