I AGREE with Emma Thomas, (HAS, May 31), particularly about drivers using mobile phones.

Is the law ever enforced; how often do you hear of someone being prosecuted for this offence?

When I see them I want to stop them and ask how they would feel if a driver using a mobile knocked down and killed their nearest and dearest. Do they even think about that? I doubt it.

The most annoying thing is that these people are usually driving cars costing thousands, when a hands free set would only cost them a couple of hundred pounds.
