Hi,
The LAW is that you must not use a hand held phone while driving, which seems a good enough reason not to do it.. A few months ago, a woman was prosecuted for using a phone while stationary in a supermarket car park. In the event, she was disqualified, but I don't know the exact details. I'm guessing that her engine was running, and she was not in a bay. What exactly is thye offence? Driving? Or being in charge of?
A public place is somewhere to which the general public have access, even if they have to pay to enter. If the place is restricted to certain people, eg: club members only, then it can be regarded as not a public place. A farmer had had a few drinks, drove home using only ROWs ....... Plod was waiting for him when he arrived home. Disqualified, but got his licence back on appeal. They kept his fine. I think he was lucky.
I understand that the police have hired HGV trucks, so they can peer into the windows of other HGVs on motorways, see if the drivers are using phones.
