Motorists are not using their mobile phones at the wheel because of peer pressure and not due to concerns about getting collared by the police, according to new research.

Using a mobile phone whilst driving has become as anti-social as dropping litter or queue jumping and has resulted in a number of angry confrontations between drivers. Last month, several motorists had their tyres slashed and a note left on their windscreens advising them not to use their mobiles while driving - the vigilante remains unknown to the Police.

Fifty-eight per cent of motorists admitted they felt intimidated by other motorists if they used their mobile phone while driving, as opposed to 38% who felt under pressure to drive legally, according to Car Parts Direct.

Mark Cornwall of Car Parts Direct said, “The possible health risks of continually having a phone to the head or even the prospect of a prison sentence for a motorist in the event of an accident has not been enough to encourage some drivers to use a hands free kit - It’s the stern stare of displeasure and a shake of the head from law abiding motorists that is helping to bring results.”

The company also called for motorists to use better quality hands-free kits, which are easier to use and have better sound quality.
