well, fine. ive no issue with folk trying to make a difference, but could you turn your efforts to preventing some serious crime, rather than pursuing 3 mph phone texters... odds are they will complete their journey without issue. odds are, they wont use the phone when sat on the A4 at 73MPH. Like you, i lost someone to a road incident, im sorry too for your loss, but these 3mph texters really are not worth your time.
