David caught the moment on his helmet camera while travelling on Pampisford Road towards the A1307 on June 10.
He said: "It makes my blood boil that somebody is willing to put my life at risk just to save five seconds."
David added: "Sitting in a van, the driver is higher up.
"If he was concentrating on the road he would have clearly seen that I was around the corner riding towards him."
He feared that if a car driver had been in his position and the van swerved, the cyclist could have been seriously injured.
Nobody is thought to have been injured during the manoeuvre.
David handed his footage over the the Cambridgeshire Constabulary.
