WE'VE all seen them do it and seethed. Those drivers who will accelerate off down a bus-only lane and sail past others who are sitting waiting in queues of traffic.

They are the same people who will impatiently try to cut in beside the bollards where motorways are reduced to two lanes by roadworks - after shooting along in the outside carriageway for a mile ignoring the stationary, nose-to-tail hordes in the other two lanes.

Such people are a real danger to other road users but are very rarely caught and prosecuted because when they offend there are no police around to catch them.

That could all change if footage from CCTV cameras already mounted on buses is used by councils as evidence to take wrongdoers to court.

And hopefully the fear of getting caught would deter many drivers from risking accidents by swerving in front of buses and clogging up their lanes.

Some will inevitably claim any such use of cameras would be an infringement of civil liberties.

But the truth is these drivers are taking liberties which threaten the lives of many others and the effectiveness of real efforts to produce an effective public transport system and relieve road congestion.
