Run Over

"What happened?" Zheng Ren yelled, opening the window between the rear compartment and the driver seat.

How could he be calm when the ambulance was not at full speed during an emergency?

"Chief Zheng, there's a vehicle in front of us blocking our path," the driver said helplessly. He had tried to change lanes several times, but a sports car in front of them had continually gotten in their way. It was impossible to outrun it, too.

Furthermore, it was approaching the evening rush hour and traffic was already building up.

Most private cars and taxis were more considerate and would usually move aside for the ambulance when they heard its siren. 

This was a life and death situation. Most people understood its urgency; reaching home slightly later or having a late dinner were nothing in comparison. If they were able to, they made way for the paramedics.
