Rob Gifford, director of the Parliamentary Advisory Council for Transport Safety, said he welcomed the trials. But he added: "Pedestrians might well say, 'What about us when we are crossing on a green man and a cyclist comes around the corner?' On one hand we want cyclists to obey the law but on the other we let them 'break' the law. It could send a mixed message to cyclists, some of whom appear not to comply with the law when they can get away with it."
