An eight-year-old girl who was left maimed by a millionaire's drug-addled son who killed two other people in a crash told a court "this stupid, ugly man has crushed my life".
Convicted car thief Joshua Dobby, 23, was out on licence when he ploughed a stolen car into Makayah McDermott, 10, and his aunt Rosie Cooper, 34, as they walked for ice-cream in south London.
He then stepped over the badly maimed body of another young child to make good his escape.
The eight-year-old, a keen cheerleader, told the court in a victim impact statement: "An ugly man's foot stepped over me and then ran.
"I constantly cry. My legs are a constant reminder this stupid, ugly man has destroyed my life."
A judge has jailed him for 12 years.
Dobby, who had 53 previous convictions dating back to the age of 13, admitted two counts of manslaughter and injuring the girl in August last year.
The victims' family said in a statement outside court: "We came here today to see justice done and in the hope that Joshua Dobby would show remorse and be sorry for killing our beautiful Rosie and our wonderful Makayah. But he has shown none."
Earlier, Makayah's grieving grandfather accused Dobby of treating his family as "worthless" and "expendable".
Martin Cooper told how he watched helplessly as Dobby lost control and launched the car at his daughter and four grandchildren.
In a statement, he said: "On that day, I was there. I watched the car drive into and over all five members of my family.
"I watched as the driver of the car made no attempt to stop or apply the brakes and no attempt to swerve.
"In front of my eyes, my daughter Rozanne and my grandchildren all became worthless in the eyes of the man driving the car, a means to an end.
"They all became expendable and their only value was to create a scene of death and destruction, forcing the police to end their pursuit of him.
"For the sake of a day or two on the run, he sacrificed the life of my daughter and grandson, killing them and mutilating my granddaughter."
On the afternoon of August 31 last year, the Cooper family were on their way to have ice creams and play on the swings.
Dobby was driving a black Ford Focus at three times the speed limit down one-way roads and jumped red lights before he lost control, hit a bollard and launched the car into the group.
He leapt out of the wreckage and fled on foot, leaving police officers to try desperately to save the victims.
Makayah died from 40 injuries and his aunt had 53 wounds while another young child suffered serious leg injuries.
Dobby was heard to shout: "I've killed her! I've killed her!" as he was pursued by police on foot.
After he was arrested, he said: "I was driving I admit it. I should have just stopped.
He was on his way to sell the stolen car for £300 to buy more drugs when he killed Ms Cooper and Makayah.
