A reckless driver who collided with a motorcyclist while trying to overtake him at Bellambi will appeal her 12 month prison sentence.
Magistrate Michael Stoddart said it was a miracle Walter Bagnarol wasn't run over by other vehicles when he was thrown onto Memorial Drive after being hit by a Toyota Camry on the afternoon of October 15, 2017.
Dash Cam footage of the incident played in court on Friday shows the Camry driver, Bulli mum-of-three Sandy Keen, travelling north in the right lane when she drives up behind Mr Bagnarol's bike, which is sitting close to the centre lane.
Keen moves her vehicle to the right of the bike to overtake, however hits the outside median strip, causing the Camry to swerve straight into the path of Mr Bagnarol's bike.
The footage shows Mr Bagnarol being flung off the bike and landing in the middle of the left lane. A motorist slams on her brakes and only narrowly avoids running over Mr Bagnarol.
Keen stops a short distance up the road. The court heard she walked back to the scene but denied suggestions she abused Mr Bagnarol, saying she only asked what he was thinking and if he was okay.
Her actions in trying to overtake in the lane, when she goes to the outside of the lane ... has had these disastrous results.
Mr Bagnarol was taken to hospital for treatment on his shoulder.
Prosecutor Amelia Wall said he had undergone two surgeries since the crash and would require more after a recent MRI detected more damage in his shoulder.
"He's in constant pain," she said.
Keen pleaded guilty to a charge of dangerous driving occasioning grievous bodily harm, with her lawyer, Caitlin Drabble, saying Keen accepted she was "100 per cent at fault".
Ms Drabble said Keen was a 40-year-old single mother working two jobs and had been distressed at the time of the incident because she'd discovered her boyfriend of two years was already married.
In sentencing Keen to prison time, Magistrate Stoddart noted she had a poor traffic record and had clearly acted dangerously on the road on this day.
"Her actions in trying to overtake in the lane, when she goes to the outside of the lane ... has had these disastrous results," he said.
"If you look at the film it's quite amazing there weren't any more serious injuries."
Keen immediately lodged a notice of appeal against the severity of the sentence.
She was released on bail until the appeal is heard.
