HEART-STOPPING footage has shown a cyclist ploughing into a car before furiously punching the driver's window in a road rage clash.
The rider was almost crushed beneath the SUV's wheels as they went into an agonising slide - but came up in a fury.
The clip, which appears to have been shot in Argentina, showed a pair of cyclists travelling along a busy main road, with traffic all around them.
The pack of bikes kept to the inside as there was no dedicated cycle lane in place.
At the beginning of the video, seemingly recorded by a helmet cam, a white SUV can be seen overtaking on the outside, giving the bikers plenty of room.
One of the riders then overtakes the person filming at speed as the car begins to pull over into the same lane up ahead.

However, with little warning, the motor then goes to turn off the road, presumably to park on the forecourt of one of the roadside shops.
It is not clear in the video whether or not the driver is indicating as they make the turn.
Either way, the cyclist ahead of the camera seemed to be taken completely by surprise, slamming on the brakes and sending his bike into a skid.
Despite his best efforts, the rider toppled over and slid along the tarmac before ploughing headlong into the side of the car.

But, far from being shaken up by the crash, the cyclist got back to his feet immediately, visibly angry at the other road user.
He stormed over to the car and gave the rear passenger door a hard kick, before punching the driver's side window.
Plenty of social media commenters insisted that he was right to be enraged.
One wrote: "Typical of a driver who doesn't think the bike is going fast.
"It is disdain for the cyclist.
"They should have gone behind in the right lane and turned when there was time to."
But others suggested the rider was going too fast to safely get around the turning car.
Another hit back: "A real [cyclist] would have avoided that and would have been in the fast lane."
