A second man on the street side was also spotted launching an object at the car as it reversed away.
The initial pursuer, wearing a hood, looked to be holding a weapon in his right hand as he ran after the motor.
The shocking incident took place on Merrick Road, Southall, London, as reported by Need To Know.

A man was arrested on Friday (13 Feb) in relation to the chaos but police are still investigating.
A local resident captured the footage from their balcony around 8pm on 7 Feb.
The silver vehicle, which at first attempted to drive down the road, floored it in reverse onto a busy roundabout to escape the duo.
The car was hit a number of times, with the driver also narrowly avoiding hitting a pedestrian whilst trying to swerve away from the men.
The attacker who first confronted the driver outside Samuelson House is reported to be a resident at the apartment building.
Later that evening, the neighbour who filmed the incident from the balcony spotted three police officers in the corridor.
Filming through the peep hole, a trio of cops can be seen battering down a door that is believed to be the hooded man’s home.
