This dashcam footage from Australia shows a Volkswagen Golf driver brake-check another motorist, before embarrassingly thudding into the rear of a stationary Mercedes-Benz at the next set of traffic lights.

The clip, which was captured in Sydney, starts with a little hooting, presumably from the black Golf that is at that point out of shot. The VW driver then pulls ahead of the camera-equipped vehicle before slamming on the brakes.

The two drivers then begin remonstrating as they head towards an intersection. But the Golf driver is so fixed on the argument he fails to notice a silver Mercedes sitting in traffic ahead, slamming into the back of the German sedan. Ouch.

Watch the footage above but be warned it contains strong language…
