We've covered plenty of helmet camera footage here on road.cc involving cyclists being assaulted by other road users, but here's something different - a cyclist slapping a moped rider as the pair pass each other on a cycle path.
The incident took place in Stockholm, Sweden and the video was uploaded to the website LiveLeak last Wednesday by the moped rider, where it has been viewed more than 60,000 times and attracted around 900 comments.
After sending the moped rider crashing to the ground, the cyclist protests his innocence as a passer-by berates him, saying, "You can't just punch people!"
"I didn't punch him, absolutely not!" he replies, according to the subtitles.
A punch or a slap, semantics aside the footage clearly shows the cyclist raising his left arm to hit the moped rider as the pair approach one another from opposite directions.
The moped rider explained in his post that he was legally entitled to be on the shared-use path, saying: "The lane to the right is actually for pedestrians, while the lane to the left is for bicycles/mopeds going both directions."
The presence of mopeds on paths primarily meant for bicycles is often a source of tension between users of both types of two-wheelers due to the typically higher speeds mopeds travel at, the noise they make and the fumes they emit.
A law currently going though the Dutch parliament will allow municipalities to ban mopeds from cycle paths, with Amsterdam, where use of the powered vehicles has boomed in recent years, among cities planning to do so.
