Two of the victims of the hit-and-run incidents in Cardiff last year had to leave the court room when footage was shown of them being dragged under the van that the defendant was driving.
Gill White and her daughter Rebecca were two of the most severely injured victims in the attacks.
A court in Cardiff is hearing how defendant Matthew Tvrdon told police he thought something might have put in his food which caused him to drive so erratically and target five separate families.
He also claimed in police interviews that he was merely trying to drive the van to somewhere quiet so he could get some sleep.
Doctors have agreed he was suffering from a mental condition known as "gas lighting". The defendant himself says he was aware of suffering from the condition, which he researched on his own computer.
Cardiff Crown Court has heard how a man who went on a hit-and-run rampage through the city last year did not intend to kill any children, although he targeted five different families.
Matthew Tvrdon, 31, is due to be sentenced later today after pleading guilty to one count of manslaughter by diminished responsibility, and a slew of other charges.
The court heard how all of those hurt in the incidents were strangers to the defendant, and were in places where they should have been safe.
A van driver, who admitted running down and killing a mother-of-three in a hit-and-run frenzy in which 13 other people were injured, is to be sentenced today.

It has emerged that the mother who was mown down and killed in Friday's hit-and-run rampage in Cardiff saved the life of her children before she died.
Her brother said Karina Menzies, 32, was walking outside the fire station on Cowbridge Road West in Ely with her children when a white van was driven straight at them.
Ms Menzies bravely threw her children out of the way, her brother Craig Menzies told Radio 5 Live.
"He went through the traffic, aimed for them and then just hit them head on," said Mr Menzie.
He added: "She just screamed and threw them out of the way as much as she could.
"He still clipped them but she took it head-on. She saved their lives."
Two of the injured adults were in a critical condition and five children were also receiving treatment.
Reverend Jan Gould is giving a reading during a church service for victims of Friday's hit-and-runs. She said: "This is perhaps the deepest grief that we have shared as a community".
She added that Friday's events have "broken the heart of our community".
