This dashcam footage from Australia shows an angry Mercedes-AMG driver brake-check a Mazda6 wagon, cause a collision and then simply drive away.

The clip was filmed on the M7 highway in Sydney, New South Wales.

It shows the AMG-badged Mercedes-Benz C-Class coupé “undertake” a string of vehicles sitting in the right lane, before cutting in ahead of the Mazda and slamming on the brakes.

As a result, the flat-bed bakkie behind the Mazda locks up its brakes and clatters into rear of the Japanese stationwagon, before the person behind the wheel of the Mercedes simply drives off, gesturing out of the window.

Watch the footage below, but be warned that it contains a sprinkling of strong language…
