Re: Ban? What ban?
"I still regularly see erratically driven vehicles being driven by someone with a phone clamped to their ears. Unless you have a policeman on every street corner then it is hard to get these morons to stop."
If you regularly see it, then you need to get a dash cam fitted to the rear window, capture them with their plate talking on the phone and report them to the police. Just your footage is enough to get them "convicted".
It is physically impossible for the police to have an officer around all the time (unless you want to pay a lot more tax) so people need to stop moaning that there aren't enough police around to enforce the more minor laws (i.e. the ones that don't involve direct confrontation of the person committing the offence) and start to do something about it themselves.
