I drive professionally and would never use a phone however it is wired. No call is that important. Pull over if necessary. True I am an old arse and remember the dark days before most people had a phone, never mind a mobile one but somehow we managed!
That's a load of rubbish!
Talking on the phone whilst driving, using a bluetooth connection to the car, is no dangerous than talking to a back seat passenger. And less dangerous than fiddling with the radio etc.
Credit some people with the ability to drive safely and talk at the same time.
This ban will never happen. next they will ban you from laughing whilst driving which is more of a distraction than talking.
