A man has been sentenced to a minimum of eight months in jail after he was caught driving his BMW in Sydney while more than six times the legal alcohol limit.

Businessman Matthew Duncan, the former CEO of multi-million dollar luxury car retailer Trivett Automotive Group, was captured on CCTV struggling to get out of his car on Bland Street in Woolloomooloo last year.

In court today, Magistrate Susan McIntyre said it was “sheer good luck” the repeat drink-driver hadn’t injured or killed anyone.

Duncan handed over his phone before he was handcuffed and led out of court.

It was last November when the former chief executive nearly hit an Australian Federal Police car in Woolloomooloo.

He was later captured on CCTV stumbling from the driver’s seat of his BMW. He tried to steady himself but failed and fell to the ground.

Neighbours eventually came to the aid of Duncan, 39, and helped him take a seat in his vehicle.

When officers found him he told them he wasn’t driving and hadn’t been drinking.

But the court heard he was slurring his words, swaying and had one eye closed.

There were also three 50ml bottles of vodka in his car.

He was taken to Kings Cross Police Station for a breath analysis, which returned a reading of 0.342.

Duncan had only started driving again seven months earlier, following another high range drink driving conviction.

His lawyer argued “it has been the wake up he needed and it has turned him completely around… four months alcohol free.”

But Magistrate Susan McIntyre expressed shock that he “could even manage to drive a vehicle let alone speak.”

She added “the court wonders however how many opportunities it is he wants…”
