(Video) Nine cars raced inside Kai Tak Tunnel

At least nine cars raced inside Kai Tak Tunnel and crossed the double white lines while overtaking other vehicles. 

According to a 19-second video which went viral on Sunday, nine private cars were going in high speed on the right lane. They crossed the double white lines to their left, and then shifted back to the right lane after overtaking a cab. 

The driver who filmed the video joked that the last vehicle was "polite", as it flashed turning signals when changing lanes.

The dangerous race agitated netizens. 

"Lawless! Suspend their licenses!" one said. "Report them! Being nice to them means cruelty to other road users," another added.

Others joked that the vehicles were not luxurious models this time, and that it was a “civilian” version of illegal car racing.  

Last week, nine men and a woman were arrested after videos of  illegal racing in Fanling emerged on the internet. Nine luxurious sports cars were seized.
