She pulled up beside the police at a set of Albury traffic lights, began yelling at them to get their attention then put her "boom box" outside her car window with the music at full volume.
When the lights turned green, 68-year-old Julie Anne Gladwin revved her engine hard and, the police witnessed, "accelerated harshly, causing the front wheels to lose traction".
The small, plainly dressed and bespectacled West Albury woman - who pleaded guilty in Albury Local Court on Monday, though was armed with a school note book in which she had written down the excuse for her behaviour - wasn't finished.

Gladwin then accelerated away from the David and Swift streets intersection, on April 29 at 7.20am, "at speed".
Moments later though she pulled over for the officers, parking by the side of the road.
Gladwin got out and approached them "in an aggressive manner" before getting back in her car.
"(As) police were conducting checks, she revved her engine whilst yelling for police to 'hurry the f ... up'."
But Gladwin told magistrate Rodney Brender that she had been suffering from issues that 10 days later had her admitted to Albury hospital's mental health unit Nolan House, where she stayed for three weeks.
Mr Brender said he was prepared to accept the health circumstances provided context to Gladwin's behaviour towards police, which resulted in a charge of start or drive vehicle causing unnecessary noise or smoke.
He dismissed the charge under Section 10 (1)(a) of the Crimes (Sentencing Procedure) Act.
But on two charges laid over an incident four hours later where she turned right from the wrong lane of Young Street, while also disobeying a red turning signal, she was convicted and fined $300.
