A Gold Coast man has apologised after sharing shocking footage of a woman drinking a bottle of wine in the driver's seat of her car.

“She actually pulled out a full bottle of wine, sat back and drank the entire bottle in one go,” Sam Mangan, who took the video, told 9 News Gold Coast.

“It was unbelievable.”

Soon after the video was taken, the woman allegedly caused a three-car pile up and returned a blood alcohol reading of 0.276, more than five times the legal limit.

People were quick to slam the footage, saying people had no idea what she was going through.

“Ever asked what she was going through and what drove her to do that?” Asked one person.

“You posted about her without knowing any history … agreed she should not be drunk driving [but] you know nothing of what that woman has gone through that day,” the person said of the video, in which Mr Mangan doesn’t identify the woman or show her face.

Despite Mangan initially saying that he didn't agree with the critics, he has changed his tune.

“If you’re going to drink enough to (allegedly) be five-and-a-half times the legal limit and get behind the wheel of a car it becomes anyone’s business that’s going to stop you,” Mr Mangan said.

“If you’re stupid enough to drink drive you deserve to be caught.”

He later posted the video footage on his Instagram, saying that he was glad "this all ended with no one getting hurt".
