Pretty much the same thing happend at Arena at start of season when Hans passed Leigh Lanham on the inside and Leigh dropped it, there was possibly a little minor contact as per last night but some riders find it all to easy to just take a dive than stay on knowing they will lose a race position.
Hans understandibly a very frustrated rider because every time he gets near another rider of lesser ability they expect the worse and are almost waiting for that chance, its almost as bad as diving in football, soon riders will be too afraid to try and pass for fear the other will simply take a fall.
