'Old enough to know better': Elderly duo in violent road rage brawl

Two elderly men have been filmed engaging in a fist fight in the middle of a Sunshine Coast road.

In the video, recorded on Wednesday and shared today by Dash Cam Owners Australia, a grey four-wheel drive can be seen tailgating a charcoal-coloured sedan.

The four-wheel drive eventually uses a right-hand turn lane to illegally overtake the sedan.

The sedan swerves to the left to avoid being hit by the four-wheel drive and then speedily follows the other driver in turning left, without indicating.

As the third driver, whose car was equipped with a dashboard camera, follows them around the corner into Sahara Road, Glass House Mountains, both cars are parked and blocking traffic.

The driver of the four-wheel drive, wearing a blue shirt and navy blue shorts, then approaches the sedan driver, who knocks him to the ground.

The yellow-shirted sedan driver then assists the man in the shorts off the ground, but is struck by a closed-fist punch to the head.

Both men were embroiled in the fist fight for close to a minute.

At one point, the man wearing the shorts was almost knocked on to the nature strip after tripping backwards on one of his thongs.

"Apparently it started earlier, but I caught up with them on the railway bridge in Glass House Mountains," Stefan, the man who shared the video, wrote.

"They are old enough to know better."

There is no active police investigation underway as neither man has filed a complaint.
