Sanctimonious, Moi?
I did initially consider that such technology may help drivers operate in accordance with the rules and, as such, could prove beneficial. However, if the objective is to compensate for a lack of focus the contrary proves true. In fact, it could promote irresponsible driving if used as a substitute for paying due care and attention. I'm not opposed to the use of such technology and I often use the cruise control function of my own motor car as a speed limiting device but I do so responsibly, using it as an aid to focus rather than a substitute for the same.
In reality drivers will get away with complacency most of the time, it's that one time in a million the unexpected occurs that dictates a need to be fully focused all of the time. Any momentary lack of focus has the potential to cause serious injury or worse. You could be lucky and kill a white male over 25 with no ceoil talent and no GAA related sporting prowess... or you might not be so lucky.
Enforcement, enforcement and more enforcement is what's needed to promote the safe operation of motorised vehicles.
