When Hayden Currie T-boned another car at 149km/h, killing two people and paralysing his friend, he didn't call triple-zero.
His first call was to his father about his car, then he phoned a mate to say he'd had a bad accident.
Currie, now 20, was doing 168km/h in the suburban Melbourne street last September with three passengers in the car before he slammed on the brakes.
He regularly drove at extreme speeds - a dashcam showed him hitting 178km/h just weeks earlier.
Shannon Juriansz was driving his prized Nissan Skyline to help a friend when Currie's car smashed into his drivers side, crushing it.
His car was pushed more than 60m down the Oakleigh West road and burst into flames. The 20-year-old was killed instantly.
Currie's car also went flying down the road, crossing a concrete barrier to the wrong side of the road.
In the back seat were his mates, Lucca Smeraldo and Jacinta Barnett.
Ms Barnett, 19, was rushed to hospital with significant injuries. She went into cardiac arrest in the ambulance and was taken straight into surgery but died a short time after.
Mr Smeraldo, then 18, suffered a spinal fracture and is now paraplegic. His jaw and ribs were also broken and he continues to suffer from serious ongoing health issues as a result.
Front seat passenger Elizabeth Jackson suffered a broken sternum while Currie escaped with minor injuries.
Mr Smeraldo told police that Currie had a reputation for breaking the speed limit. He can't remember the crash, but said he'd often told Currie to slow down, especially when they had girls in the car.
Analysis of dashcam footage found Currie had been excessively speeding 13 times in the previous weeks, including hitting 178km/h in a 70km/h zone while drag racing.
Ms Barnett's mother said she hoped her daughter's death sent a message to young people to really trust their drivers.
"You were responsible for keeping your friends safe," she told Currie in the County Court.
"You killed two people, you paralysed your best mate - why can't you take responsibility for the hurt you caused?"
Mr Juriansz's father said his son was a good boy who was the link that connected their family.
It made him angry that Currie hadn't shown remorse after the crash, and had first phoned his father about the damage to his car.
Mr Juriansz's brother said they'd aspired to run their own car business together, having worked together on the Skyline. They wanted matching cars when they were older.
"I don't think I can do it myself," he said.
Currie has written an apology letter to the families, but prosecutor Angela Moran said on Thursday they weren't interested in receiving it.
He pleaded guilty to two charges of culpable driving causing death and one each of negligently causing serious injury and two of reckless conduct endangering death.
The pre-sentence hearing is continuing.
