Driving instructor has arm broken by road rager mid-lesson

An English driving instructor has had his elbow broken after becoming embroiled in an argument with another driver during a lesson.
Chris Barnett, from Essex, was sitting in the passenger seat giving a 17-year-old a lesson in mid-June when the pair were beeped as the learner struggled to pull out at a busy intersection.
After continuing down the road, their car is cut off by a white Range Rover, which stops in front before a man emerges.
"I've got you on camera, pal, what are you beeping at?" Mr Barnett says.
With the learner watching nervously, the men swear at each other before another man gets out of the Range Rover and approaches the car.
"Get back in the car, old man," Mr Barnett, 64, says, before grabbing his phone to call police.
He then opens the door, but it's slammed shut by one of the men, breaking his elbow.
A 39-year-old man was interviewed by police but no charges were laid.
