On Route 66 in the Guanyin District of Taoyuan City, Taiwan, a street racing crash caused some deaths and injuries.

At 12:35AM on September 17, 2021, 34-year-old Hong Nan was in his BMW when he decided to race a 26-year-old man named Qiu. When passing through the 9th section of the Guanyin District Expressway along the Tai 66 Expressway towards Daxi, the monitor screen showed that Hong Nan was driving at a speed of 100 miles per hour. In the inner lane, there was a car next to it. After being overtaken on the road section where the incident occurred, Hong Nan's vehicle suddenly deflected into the outer lane, skidded and flicked, hitting people and vehicles on the side of the road.

After being hit, one of them flew to the roadside guardrail, causing serious injuries to a 27-year-old man named Liu and a 36-year-old boy named Tong and who both died; 28-year-old Gao, a 25-year-old named Liu, and a 22-year-old female named Lai had multiple bruises on their bodies. They were not seriously injured after being sent to the doctor. Hong Nan who caused the accident was slightly injured. When the paramedics arrived, he refused to be sent to the doctor.

Three people who gathered outside the vehicle to chat were injured, two were killed, and four cars, BMW, Mercedes, etc were damaged.

From the long brake marks at the scene, the entire rear end of Hong Nan's BMW car was dented, the front chassis of the car was damaged, and the crowds and cars gathered at the scene late at night, the police suspected that Hong Nan was out of control and caused the accident.

After the incident, Hong Nan and Qiu Nan both denied racing, and the police still transferred the two people to the Taoyuan District Prosecutor's Office for investigation based on public danger and negligence causing death.

It is reported that Hong Nan only bought this second-hand BMW in June this year and had been sent for repair. Hong Nan argued that he was only going to test the car and see the condition after repairs. He denied racing behavior and did not know the people gathered on the roadside; the police followed the line and found the owner of Qiu, who was suspected of racing with Hong Nan, but he also denied racing. The police transferred the two people to the local investigation office. The prosecutor and the forensic doctor examined the body of the deceased last night to clarify the cause and responsibility of the accident.
