Ms Verona Murphy:

A scheme must be workable and use technology that cannot be manipulated. Mobile phones are the root of all evil. Whether one is walking or driving, mobile phones should be placed in a stationary position. Do not get me wrong, I am no angel when it comes to mobile phone usage and I have tried to improve my behaviour. Mobile phone usage can be manipulated. The Chairman thought that maybe one's granny could take the phone. The person concerned could have a second phone and that is the trouble.

If a person decides to try to avoid getting penalty points and leaves one phone stationary, where is the other phone that he or she may have?
