Motorists said they were tired of criminals who used top traffic to throw them.
They want the police and the metro police to redouble their efforts and detain criminals.
"If government officials don't start their jobs properly, more and more citizens will end up taking their own hands." Vigilantism will be the norm, ”said motorist Simphiwe Mahlung.
The City of Joburg MMC for Public Security Michael Sun said they were aware of robberies and received complaints. He said they were working on robbery.
"We already have an operational plan," he said.
Metro Police spokesman Wayne Minnaar said: "We learned about the situation on Friday through social media.
"The subconscious officers have been deployed to monitor this area today (Monday)."
Another motorist Limukani Hadebe shared with Star as he once witnessed a robbery.
"We were in traffic and this young lady who drove the white Polo behind me was robbed." Two boys walked as if they were walking down the street, and I was shocked to see one of the guys going into the car through the open window while the other one was holding the lady back and slapping her. It wasn't even quick, it was as if they knew the traffic would take a long time, "Hadebe said.
Social media users considered on Twitter, with @illegaladverts saying, "He's been doing this at this crossroads for years. Motorists guard, armed robbery, just another day in Joburg. "
@ Karabomophiring tweeted: "The problem is that when you go to SAPS to report a crime, that's all you do … writing an affidavit for insurance or anything else." No investigation data for hotspot mapping and trend detection. It seems too much work. "
Sun urged motorists to be cautious and alert when approaching known crime sites.
