This dashcam footage from Australia shows tempers flaring as the drivers of a Hyundai Tucson and Hyundai H-1 van (known Down Under as the iLoad) attempt to merge into the same section of road.
The video shows the two vehicles moving slowly alongside one another, with the gap between them becoming increasingly narrow.
Neither driver is prepared to give way and at one point the two vehicles appear to touch lightly.
After plenty of remonstrating, a passenger climbs out of the window of the Tucson and bizarrely straddles the two vehicles. As he clambers back into the SUV after having a closer word with the van driver, the latter pulls ahead.
Watch the footage above … and take it easy out there, folks.
