A disgruntled cyclist was caught on camera repeatedly swerving across the road and slamming on his brakes to stop a driver from overtaking him in a 20mph zone.
Driver Sam England, 40, had picked up his 12-year-old son from football when he pulled onto the A4109 near Seven Sisters, Swansea, behind two cyclists.
However the family soon noticed one irate cyclist shouting and waving at them before zigzagging across the road in a repeated attempt to stop the vehicle from passing.
Mobile phone footage shows the rider blocking the car from overtaking – while looking back and shouting – and weaving across the road and onto the wrong side.
