A Sydney man has sparked a lively debate online after sharing a simple roundabout move he says can help drivers bypass heavy traffic.

In an Instagram video posted on 11 February 2026, Sydney-based user Zane Ammar filmed himself approaching a busy double-lane roundabout where cars were banked up waiting to turn left. Rather than joining the line, Ammar enters from the right-hand lane, loops around the roundabout once, then exits into the lane he wanted, effectively avoiding the queue in a single manoeuvre.

In the expletive-filled clip, which has attracted more than two million views, he describes the move as a “completely legal traffic hack”.

Commenters were split. Some praised the idea, calling it “genius”, while others urged him to “stop sharing the secret”. Plenty said they already knew it, often referring to it as a “slingshot turn”. As one person put it, “People have been doing [this] for decades,” one commenter said.

Not everyone was impressed, though, arguing that even if it works, it is not great road etiquette. “If everyone decided to jump lanes the way you did, the same line would simply exist somewhere else,” one commenter argued.

On the legality, the manoeuvre can be allowed so long as drivers indicate correctly, give way to vehicles already on the roundabout, and follow lane arrows and road markings. There is also no set rule on how many times a driver can circle a roundabout, but repeatedly looping could still attract attention from police under broader offences. “While there is no specific offence for driving around a roundabout multiple times, the general offence of causing a public nuisance could be applied,” an ACT Policing spokesperson said.
