It's hard to imagine a more contentious set of road-safety rules than those surrounding the issue of cellphone usage by motorists.
When the rule banning people from using mobile phones while driving was introduced with much fanfare two years ago, police were insistent that it would save lives.
That insistence was regularly used to bat away the cries of outrage from a shocked public, most of whom clearly seemed to think the law shouldn't apply to them.
It's hard to quantify how much of a success the law has really been, despite reported figures claiming that between 2003 and 2008, 25 people lost their lives in crashes which resulted from people using their cellphones while behind the wheel.
By the same measure, since the law has been adopted, just nine deaths have been attributed to cellphone use.
