An Australian cyclist has uploaded footage of the frightening moment he was threatened by a knife-wielding driver.
In the video posted to YouTube, the impatient driver of a 4WD tries to push his way in front of the cyclist as they approach a roundabout -- leaving only centimetres between them.
The cyclist swerves and lightly clips the front of the vehicle before yelling "What the f*** are you doing?"
The driver then accelerates up the road before pulling over and running at the cyclist with a knife.
According to a caption on the online post, the "rather charming gentleman" avoided jail and was handed a $1500 fine.
