The social media was taken by storm by a two-minute video of the woman's act, with most people sharing the links online and lauding her.
The incident took place on Sunday evening when 23-year-old Sadhvi Pandey along with her sister was going to see a doctor on a scooty.
When they were waiting at a crossing, the cavalcade of Abhinav Sharma stopped alongside and the gunner allegedly winked at her from inside the car.
This infuriated Pandey further and she climbed on the bonnet of Sharma's Mercedes car and tore off the party flag fixed on the bonnet and used it to break the windshield.

Reacting to the incident, SP's Naresh Aggarwal said, "Abhinav Sharma is not leader of SP. This is a fashion in Uttar Pradesh, people generally carry the flag of the ruling party".
"If the gunman is found guilty, if he misbehaved then I'm with the girls. I will myself send him to jail. If it is the fault of the guard, Samajwadi party will send him to jail and Abhinav Sharma will do the deed of sending him to jail," he told a TV channel.
He, however, said that Pandey should have at least told him that the gunner had made a lewd gesture.
"I would have beaten up the gunner at the same time. But as soon as I tried to talk to her, she broke my chain, she started damaging my car. What could I have done at that time. Should I have fought with Sadhvi. She just damaged my car.
The woman refused to term her act as one of bravery.
"You could have also reacted in the same manner if anything you had purchased with your hard earned money had broken. Had they not broken my mobile and taken action against the guard, we would not have gone so extreme," she said.
A police officer said no FIR has been filed.
