A DRIVER has shown off how to cut hundreds of pounds from petrol bills with a controversial car hack which others on the road hate.
The motoring tipster has posted birds-eye footage of a car accelerating past queuing traffic with a so-called "slingshot" move.
The social media user shared the eight-second TikTok in response to others arguing over the driving tactic's merits.
Newcastle motorist Shaun Jobber used it to explain how the trick works, titling his video: "Bird's eye view of a roundabout slingshot."
But it provoked mixed responses from comments below - with some people in awe of the idea, others disgusted.
"Slingshot" drivers switch across lanes as they circle a roundabout in full before hurtling past cars still queuing for the first exit.

Shaun's account shares videos he insists should help drivers better understand unfamiliar road rules - and also cut down on petrol costs by shortening their journeys.
He previously worked as a motor insurance claim handler and uses that experience to warn about unnecessary traffic jams.
One viewers of the "bird's eye" video condemned it as "technically inconsiderate driving, misusing a lane to gain an advantage".
But they did concede it was "impossible to prosecute unless they catch you doing it multiple times".

The TikToker was praised, however, by others calling the move "absolutely genius" and also told: "I still don't get what's wrong."
Someone else admitted taking that approach "can feel rude", only to add: "A roundabout is designed to keep traffic flowing so flow on!"
Earlier this summer Shaun dubbed other drivers "stupid" after he managed to overtake 20 other cars.
There have been further examples of "slingshot" moves swerving morning traffic.
Yet social media also sent viral footage of a car's loss of control on a wet roundabout.
The latest clip follows complaints online about a BMW similarly veering between lanes at a congested Norwich roundabout.
But another TikToker has been celebrating how his "epic" slingshot move can cut 20 minutes from his journey.
