The death of 25-year-old Tan Zhuo, crushed by a speeding sports car in the hands of a 20-year-old college student Hu Bin in Hangzhou, is arguably the most high-profile road accident in recent times.

Hangzhou police claim the car was speeding at 70kph, but eyewitnesses, who saw the victim thrown meters away from the impact, differ.

The accident caused such a public outrage that T-shirts with "70mph" written on them are being sold in Hangzhou shops to mark their protest.
