Sir, - Has anyone a rational explanation for the increasing number of drivers using fog-lights in clear conditions? I can only assume they are ignorant that such use is not only illegal, but it causes considerable glare and danger to oncoming traffic, particularly in wet conditions. Do these drivers feel that a blaze of lights somehow enhances the macho image of their car? If that is so, and they require this boost to their flagging self-esteem, then I would advise them that more mature and confident drivers can only look upon them with a mixture of pity and amusement. - Yours, etc., D. O'Connor,
Enniskerry,
Co Wicklow.
