I've met a few women like her in the public in my life. They're all the same - hyperaggressive, verbally profane, secure in the knowledge that if anything happens physically the police will take their side, quick to run behind their boyfriend/husband for protection once you stand up to them, etc.
This guy's a pussy. He's the driving instructor and the car isn't hers. He should've asked her to pull over. When she refused, he should've forced the steering wheel to the side of the road , slammed the breaks, put it in park, pulled out the key and told her to get out of the car while he gets back in the driving seat. She probably would've attacked him, which would've put the law on his side and he could've had the pigs remove her from the vehicle. Instead he just taped her like a pussy, without even showing her the camera, and argued back with a lunatic so he could get "I feel you" backrubs on Youtube.
