"I suspect you're getting over excited there, Tora3."
I'm not so sure that he is.
The epidemic of people faffing about with phones and other gadgets whilst driving is completely out of hand. The current penalty (£100 and three points) is hopelessly inadequate especially bearing in mind the extremely low level of detection. The mandatory sanction of a minimum one year disqualification certainly as a deterrent effect on drink-drivers, There will always be a hard core of drivers who will drink whatever the consequences. But there is little doubt that the casual drinker certainly thinks hard before driving over the limit with the possibility of a year's ban on offer.
I'm not so sure I'd suggest an immediate life ban, but certainly a year for a first offence followed by three years for a second within ten years (as with DD) and, of course the sort of insurance grief that accompanies excess alcohol offences.
