Madam, - L-plates warn other road-users that they are in the vicinity of an inexperienced driver. Mandatory "points" plates should be used to warn other road-users that they are in the vicinity of a dangerous idiot with little regard for other road-users.
A system requiring drivers to display their points prominently both fore and aft (with appropriate points penalties for failure to do so) might concentrate minds on the socially unnaceptable nature of negligent and dangerous driving. - Yours, etc,
LOUIS OWENS, Earls Court, Old Cabra Road, Dublin 7.
