Watch as furious ‘Karen’ accuses man of polluting by leaving his car engine running – but there’s a hilarious catch

A SHOCKING VIDEO has been revealed showing a woman accusing a man of causing pollution by leaving his engine running - but there's a hilarious catch.

The driver behind the camera was left in shock after discovering that the woman, branded a 'Karen' by viewers, was going to report him to the police for 'polluting the atmosphere.'

The video was uploaded to social media by Twitter user - and starts with a woman knocking on the driver's car window.

The Karen asked the driver: "What are you doing here with your engine idling? You're polluting the atmosphere, just sitting here without caring about the world with your engine running.

"And you don't care who you're polluting here. There are a lot of kids who live around here."

The driver said: "I don't see any kids around here."

The Karen replied: "Well, they're not here at the moment, but they are living in these flats. You know the fumes of this car are going through all the windows and all the ventilation."

The driver replied: "The fumes from this car? You know this car is electric, right?

The Karen said: "Hahaha, you said your car is an electric car to cover your crimes. I will be reporting this. I have the number of the police. I will take a picture of you and your car."

The man told the Karen: "And you are standing there with a hat on?"

The Karen replied: "Well, that might be a crime against fashion, but it's not a crime as in the police are going to get me, are they?"

The driver said: "Okay, so what, you are going to call the police because I'm just sat in my car?"

The Karen answered: "If you were sitting in your car with your engine off, I wouldn't say anything about it. I will go off my way and enjoy my afternoon rather than engage in a pointless conversation."

The man then tries to convince the woman that he's driving a Tesla, but the woman doesn't believe him.

The video has gone viral on Twitter with more than 672,000 views - and most users are on the driver's side.

One said: "She's not well."

Another said: "OMG, her negativity vibes... worst than a fume."

A third pointed out: "She knew before the conversation even started, what the hell is this Karen doing?"

This comes after a shocking video showed a woman blocking a parking space to reserve it for a friend.

Plus, another driver filmed a woman blocking a parking spot, ruining a family day at the beach.
