Mr Kayardi, 33, who had been a driving instructor since 2009 and has taught over 200 people to drive, accused Mr Porter of cycling dangerously.
The motorist, who has a clean licence and no previous convictions, said he checked ahead before overtaking and did so when the road was clear and there was a safe distance between him and the cyclist.
‘I did not put Mr Porter’s life in danger. I did it when it was quite safe to do so,’ he said.
‘I did not cause any harm to him or oncoming traffic.’
But he said when Mr Porter came to confront him, the cyclist crossed over the white lines to the wrong side of the road and later ‘cut him up’ as he weaved through traffic to tell a nearby policeman.
The officer spoke to both men but let them go, and Mr Kayardi assumed it was the end of the matter.
