A dashcam mounted on the rear of a car captured the moment a motorist rammed into the back of a driver while passing through a car wash tunnel on January 7.

The collision reportedly took place on Sunday at a Wangara car wash. The driver posted footage to YouTube showing his car being cleaned by the automated car wash. Then another vehicle drives forward with its windscreen obstructed by the mitters. The impact was enough to push the first vehicle forward. Credit: YouTube/LazyPerthGuy via Storyful
