The devastated father of three of four children killed by a drunken speeding driver says "you have ripped my heart out and ran over it in your car".
"You ran my children over like a lawn mower with cut grass," Danny Abdallah said in his victim impact statement read out at the killer's sentence hearing on Friday.
But while he blamed Samuel William Davidson, he also blamed the culture which says consuming excessive drugs and alcohol is good.
"This culture needs to stop, because of this culture I buried half of my children."
The 30-year-old killed four children and injured three others when his ute mounted the kerb at Oatlands, in Sydney's northwest, on 1 February last year.

They were on the footpath walking to a supermarket to buy ice-creams.
Davidson, a professional truck driver, pleaded guilty in the District Court to the manslaughter of Veronique Sakr, 11, and her cousins, Sienna Abdallah, 8, and her siblings Angelina, 12, and Antony, 13.
He has also pleaded guilty to three charges relating to the injuries caused to the other children, including a boy who has suffered permanent brain damage.
On 1 February Davidson had been sitting poolside with his housemates drinking Vodka Cruisers and beers, having his first drink about 7am, and also consumed drugs.
He later drove erratically, swerving across the road and went through a roundabout on the wrong side before losing control of the speeding vehicle.
A report later found he was travelling up to 133km/h in a 50km/h zone and was moving about 111km/h at the time of impact.
After the crash, Davidson appeared distressed and was heard saying: "What have I done? ... I have killed people ... I am going to jail."
Leila Abdallah said her grief over the deaths of her three children and their cousin felt like her "heart had been pierced with a sword".
She went from getting her kids ready for school to preparing them for their funerals.
"They didn't deserve to die on the roadway," she said.
"Even in a horror movie they can't make one car hit seven kids."
She, her husband and the parents of Veronique have said they have forgiven Davidson, referring to their Christian faith and their hope he will find god and repent.

Bob Sakr said the only time a father should walk down the church aisle with his "princess" is at her wedding.
"Instead I carried her down the aisle in a coffin for her funeral," he said.
Mr Sakr said Veronique's only sibling was devastated by her death.
Every day he remembered his son's words at the crash scene: "How am I going to do it? How am I going to live the rest of my life without her."
Bridget Sakr said the horror of her daughter's death "will be etched in my mind, my body and my soul for as long as I live".

"Just like that, in an instant, she was gone, the future stolen from under our noses," she said.
Davidson's barrister said his client had no criminal history, although he had speeding offences, and had not been compliant with his medication for attention deficit disorder.
He read out Davidson's letter of apology which said he hated what he had put the families through and prayed for them every day.
"I wake up sad every day knowing I am responsible for this and it really doesn't get much worse than this."
Prosecutor Frank Veltro SC described Davidson's moral culpability as "extreme", saying there was an absolute and complete abandonment of responsibility on his part, causing a significant risk of death to those in his vicinity.
Judge James Bennett, who noted the deep faith and commendable forgiveness shown by the families, will sentence him on 9 April.
