cyclist incident

[topgear]

I was dropping off my mate's work van (Toyota Hiace) and was waiting at the signals on the left lane. (In Melbourne) Then a cyclist came and was waiting at the signals as well. Approximately 100mts (4 car spaces I guess) after the intersection there were cars parked on road side which means I have to merge right.

So, at green me and that cyclist took off and then I overtook him at the intersection itself (not because he will get on my way but I have to merge right soon after the intersection. So, I went past intersection and the cyclist was following right behind me and I was trying merge right and slowed down as no one giveway to me and cars were a head of me and eventually someone let me go so I didn't had to stop.

While merging into right lane I noticed in the left mirror that at the left rear end the cyclist was leaning on the van. I thought he lost balance or may didn't had no where to go as there were cars a head so whatever, I immediately pulled over and waited for the cyclist and asked him if he is ok.

To my surprise, he blames me that I almost caused a severe injuries to him. He was old and out of respect I said 'am sorry mate I didn't know what happened back there, I saw you fumbling and fell on the van so thought to check if you are ok'. He blames me again and says 'you know what.. am gonna complaint to police about you for driving recklessly'. I didn't know what to say whether to laugh or to get angry and he didn't let me speak and took van rego and took off.

I have been driving for many years with no offense or fine with clean record and never faced this kind of situation. I usually stay away from cyclists as I know how vulnerable they are.

What will happen if he complaints? Is this gonna be a big issue that I have to worry about?
