A word of warning: the video we have for you above is not for the faint-hearted. Also, if you have any concerns about the condition of your car's brakes and/or gearbox at the moment, you may want to get them sorted before you click play.
The footage comes from the dashboard camera of a Hyundai Sonata YF sedan on a street in South Korean city of Daegu, with a couple driving down the road when suddenly the vehicle starts accelerating violently up to around 118kmph (74mph).
Careering down the tarmac, it was only a matter of time before it ended up in the back of a far more static object - in this case, another vehicle.
As for what the car's occupants said during the event, the only intelligible words - that aren't expletives - are "What's wrong with my car? What's wrong with my car?"
Daegu Police are now investigating the accident with the help of the National Institute of Scientific Investigation, looking into what could have caused this sticky accelerator pedal incident.
Of course, this isn't the first time something fairly spectacular/gripping/downright worrying has been caught on a dashboard camera. Check out our collection below of some dash cam footage classics...
