Mike opened the car's glove compartment, took out a handgun, and then he took out his cellphone.
After gripping the gun in his hand, Mike made a gesture, prompting Yang Yi to immediately slow down, brake at a speed that was sure to anger the car behind them, and then he immediately turned on the left-turn signal and pulled over to the side of the road.
In the United Kingdom, traffic drives on the left, so turning left and pulling over to the left is convenient, but the black sedan ahead was driving on the right-most lane of two, requiring a much larger maneuver to turn left or stop amid traffic.
The black car ahead didn't stop or show any sign of turning, and simply drove away.
Seeing the car drive off without any abnormalities made Yang Yi doubt for a moment whether he was being overly cautious, to the point of mistaking common occurrences for something unusual.
