He used bad language and allegedly broke a side mirror on the car
A video has gone viral on the Internet showing a foreign motorbike rider blocking a car and insulting the driver.
The dashcam video captured shot at 10:45 a.m. on Thursday showed the man, who did not wear a crash helmet, tried to block the car traveling on an overpass over Hanoi's Vinh Tuy Bridge.
Both vehicles stopped on the street.
He looked angry and could be heard swearing at the car driver.
Ngoc Cuong, the car driver, said he was driving on the car lane when the foreigner kept honking from behind, probably trying to overtake the car.
Cuong claimed the foreigner also broke a side mirror of his car.
