Shocking footage of a driver chasing another car through the streets of Shanghai at speeds of more than 110 mph has sparked online outrage in China.

According to local reports, the dashcam video was uploaded on Saturday and two people, including a former racing driver, have since been arrested.

Speeding has become a controversial issue in China in recent years.

There have been an increasing number of accidents involving supercars, as more wealthy people are able to purchase them. Sales of supercars are said to be booming in China.

A Porsche's reckless driving at speeds in excess of 180 km/h in heavy traffic on Shanghai's middle ring road was exposed in a video published online last weekend. A Nissan Infiniti pursued the Porsche, filming the dangerous driving with a dash cam while also accelerating far above the speed limit. The video promptly went viral, unleashing debate and criticism on social media about the drivers' crazy behavior and disregard for the safety of other cars on the road. Both drivers involved were later detained for dangerous driving.
China's ultra-rich are growing in number and in wealth in recent years, and luxury cars are one of the most obvious vehicles for flaunting their wealth and lavish lifestyles. There have been an increasing number of reports of road accidents involving supercars, attracting wide attention in China.
In April 2015, international media reported on a “Fast and Furious” style race in Beijing that resulted in a high-speed crash between a Ferrari and Lamborghini – the young drivers escaped alive as they were criticized as members of the “fuerdai” rich second-generation, and were both arrested for dangerous driving.
In 2012, Ling Gu, the son of disgraced politician Ling Jihua, was killed in a high-profile Ferrari crash in Beijing, sparking huge controversy on social media.
There have been countless other stories of supercar accidents in recent years, coinciding with a big growth in sales in the country. Bloomberg reported last year that sales of supercars in China were booming, with Mclaren announcing that it expected sales to double within a year. Meanwhile, between January and June this year, Lamborghini announced it had just gone through its best period for sales in its history, with China now its fourth largest market.
