I have never done that.
Seriously. My wife berated me for it several times, but I am not about to waste my time or gas to go back for a phone that I rarely ever need.
She is angry because she can’t get me on the phone everywhere.
But in reality, 90% of the time she can get me in my office or at home. It is only in transit between that I am unavailable for the majority of that 10%
I personally would rather not talk on the phone in the car.
