A cyclist was grabbed and repeatedly punched in the head by a driver who was angry that they were riding side by side.
Footage shows the driver sounding his horn as he overtakes Ady Short and seven other cyclists, some of whom are riding two abreast, which it legal on UK roads.
The Nissan then slows down as the driver gesticulates and remonstrates out of the car window at the cyclists on a road near Swindon in Wiltshire.
Mr Short puts his hand on the vehicle’s wing mirror to try to keep pace with the car as he tries to talk to the driver.
At this point the driver grabs his arm and repeatedly punches him in the head, sending him falling onto the road.

The rider’s wife Mandi, who was ahead of him and was filming, fell from the saddle during the confrontation, and Mr Short claimed she was knocked off by the driver.
Mr Short and his wife were with six other members of the Swindon Wheelers club when the incident happened.
He said he and his friends were on a narrow, bendy section of road when the black Nissan closed in behind them.
He said: ‘He followed us for about 90 seconds, overtook us and braked hard in front of the group, causing us to swerve around him but as we rode around him he took off again within the group, causing further issues whilst remonstrating about us not singling out.
‘(He wouldn’t have got past one person let alone eight through the bendy section).’
Mr Short said he is the club secretary and trained how to de-escalate any situations, adding ‘so normally (happens too often) we wait to hear what they say and then explain why we were riding two abreast.’
He told cycling blog, Road CC: ‘He was very angry as you can see but before I could explain he started hitting me, I just suffered a black eye as a result and didn’t actually get the chance to say anything before he hit me.

‘He also knocked my wife off her bike, the camera was hers and she suffered cuts and bruises but wasn’t considered part of the case as the police couldn’t actually see her.
‘We made the guy wait as the police were called and told him when he tried to drive off that he would end up in more trouble.’
Mrs Short told the BBC: ‘It was pretty scary. I was thinking “my goodness, if he moves forward any more this is really going to hurt and it could be quite life changing for me”.’
The Highway Code currently states that cyclists can ride side by side but should ‘never ride more than two abreast, and ride in single file on narrow or busy roads and when riding round bends.’
However, cycling organisations have campaigned for changes stating that it is sometimes safer to ride two abreast when cycling in larger groups on narrow lanes.
Wiltshire Police said they were called to the incident and gave the motorist a caution.
A spokesperson said: ‘In line with national policy, in cases of common assault with no injury, where the offender is identified and fully admits the offence, then an adult caution is deemed a suitable outcome.
‘We are committed to providing a high level of service for all victims of crime, and if any victim is dissatisfied with the service they have received then they can make a formal complaint via the Office for the Police and Crime Commissioner.’
