I think the current legal are probably adequate. The problem with all laws is the enforcement – will it achieve it’s aim? I don’t think a total ban would proportionately improve the actual road accident figure. We now have a figure which has been tried and tested over decades. My gut instinct is that total ban would probably turn out to be more of a gesture than a real improvement.
It would accelerate the change the face of British culture and close even more pubs. It wouldn’t affect the number of road accidents due to tiredness, inattentiveness, aggression, incompetence or just random error.
I think far greater improvement is likely to come from social changes to our attitudes to driving rather than drinking, not just on the part of drivers but also cyclists and pedestrians, many of whom seem to think they are invulnerable.
