THE son of pokie machine king Len Ainsworth has escaped a jail term for driving up to 152km/h in a 60km/h zone, with a blood alcohol level of 0.21 - four times the legal limit.

Today The Daily Telegraph Online can reveal video of Christian John Ainsworth screeching down the road in his V8 Range Rover Sport. Follow the link below right.

Manly Local Court Magistrate Andrew George ordered the 36-year-old must complete 200 hours of community service, and pay a $2200 fine for his high-range drink driving offence, which police caught him doing on January 28.

Mr George also suspended Ainsworth's driver's licence until 2013, when he faced the court yesterday.

Mr George had previously warned Ainsworth that he was eligible for a custodial sentence for his three charges of a high-range PCA, reckless driving in a dangerous manner, and exceeding the speed limit by more than 45km/h.

Ainsworth's defence lawyer told the court his client was suffering from depression and was on medication for his illness.

Highway patrol officers first clocked Ainsworth speeding across the Spit Bridge at about 10.30pm, when he was allegedly heading to his Mosman home.

After pursuing him, they pulled him over on Stanton Rd where he was breathalised, and he told police he "could not work the cruise control", when questioned about his speeding.

Police reported that Ainsworth had two male passengers in the car at the time, he smelled of liquor, his eyes were bloodshot and he was slurring his words.

The police documents said: "The accused admitted to having an unknown quantity of Carlton Draught full-strength beer and had numerous shots of sambucca, Cointreau and vodka with friends following Australia Day."

Pedestrian Council of Australia chairman Harold Scruby described the sentence as "a scandal", and he planned to request the NSW Police Commissioner to appeal the court's decision.

"What speed does a person have to do to get a custodial sentence?," Mr Scruby asked The Daily Telegraph.

"This is why the road toll is so high."
