A well-dressed man has been branded an 'idiot' after he was seen clinging onto a moving truck and running in front of oncoming traffic. The daredevil was spotted holding onto the back of a horse transport truck that was driving down a busy motorway near the Morphettville Racecourse on Monday afternoon after the Adelaide Cup. As he jumped off, the man then rolled across the ground only to then sprint across the road and dodge oncoming cars heading straight towards him. Miraculously, he managed to make it to the other side unharmed.
