A motorist named Sean was travelling along a steep double-line road in Malabar, south east of Sydney, when he came across a white vehicle stopped in the middle of the road.
A man can then be seen struggling to get out of the car, seemingly to confront Sean and his family. But as the man sets foot onto the road his car begins rolling backwards down the hill.
The man tries to recover and put on the handbrake while the car is moving, but falls to the ground. He rolls down the hill on his back, losing a shoe in the process.
A loud thud is heard when the white vehicle slams into Sean’s car.
