I pointed out to him, that as the holder of a Private Pilot's Licence,
when landing my plane I controlled it with my left hand on the control
column, because my right hand had to be on the throttle, so I didn't
really think that steering with one hand for a short distance in the
slow lane was that risky (or words to that effect). Half way through
this, I wondered if I should have kept quiet, but he mumbled general
cautionary phrases and went off. Phew!

Yeah, I was pulled over by an unmarked car 6 years ago, they had a tape
of me doing 87mph too. Gave me a £20 fine.

I rarely speak in the car, even with hand free.

As for the original point, they bad guy in "Marian, again", on ITV
recently, was pulled oevr for using a mobile phone.
