"The driver lurched his car forward, forcing my bike wheel and almost my leg under the front of his car," he wrote.
The cyclist said he was "dumbfounded at how overtly aggressive the driver had been". He said that after the incident Warne did not stop to check if he was injured and he claimed to have witnesses who could back his story.
Warne denied a witness report that he intentionally clipped the cyclist after the argument.
"That's factually incorrect," he said.
"He [the cyclist] was lucky, I was actually polite and careful after smacking my car twice and grabbing on to my car ... otherwise I might have put my foot down and tried to hit him.
"People can say whatever they want; I know what happened, I did the right thing at the time and I did the right thing afterwards."
Warne said he would be willing to work with cycling advocacy groups after he was criticised for inciting hatred towards cyclists. AAP
