Minty, but that has always been the case, but no law stating that you cant eat, Sorry, not being pedantic, I just wasn't sure if the law had changed.
Its a bit like driving with one arm out of the window, Ive always done it and most likely always will, a policeman has never even mentioned it.
As for the smoking with kids in the car, I dont suppose the Police will be actively pursuing it, however if they stop a car for any reason, and their is someone in the car smoking with kids in the car, they can the be prosecuted, I dont think that will be much of a drain on Police resources.
