A video showing two cars racing dangerously with each other along the Kallang-Paya Lebar Expressway (KPE) and almost causing an accident on Wednesday, has gone viral on YouTube.
In the 69-second clip, which has been viewed at least 41,000 times, a red car emerges from the left of the frame and cuts into the path of the car with the video recorder.
Seconds later, a black car hurtles from the right and makes a dash for the same spot in the middle lane.
It comes very close to ramming into the red car, which seems to be a Mercedes-Benz, before quickly swerving to the right - into the path of another car.
The video, which was filmed at 4.38pm and uploaded by a user named Cory Tan, goes on to show the black car, believed to be a Hyundai Tuscani, weaving in and out of lanes without signalling.
The drama continues after the cars emerge from the tunnel near the Tampines Road exit. The black car is shown veering into the path of the red car, once again coming close to ramming its side.
Most netizens were horrified by the attitude of the drivers and urged the person who submitted the video to send it to the authorities.
Anyone with information about the incident can lodge a police report.
