AN unlicensed teenager who was driving his dad's car videoed himself on his mobile phone just moments before he killed a 70-year-old grandmother in a high-speed crash.

The 18-year-old, who cannot be named for legal reasons, taped a video-call to a friend of himself revving the engine while saying, "130, 140'' and taking footage of the speedometer.

The crash, on April 30 last year, instantly claimed the life of Freda Page, of Winchelsea, Victoria.

In the County Court yesterday, the offender was jailed for a minimum of three years.

Judge Howard Mason said the hoon's "mindless thrillseeking'' had taken the life of a much-loved wife, mother and grandmother.
"This was not a case of a moment's inattention, this was a sustained indifference to the safety of other roadusers,'' the judge said.

The teen pleaded guilty to culpable driving and negligently causing serious injury.
He jailed the teen for six years with a non-parole period of three years.

At the request of his lawyers, the judge requested the adult parole board consider housing the teen in a youth justice centre.

Ronald Page was driving with his wife Freda in the passenger seat on the Bacchus Marsh Rd when the impact occured.

The court heard Mr Page did not brake because he did not see the offender's Nissan Patrol utility approach them at 140km/h.

"We were having a lovely drive and the next thing I knew, the glass was breaking,'' Mr Page said in a victim impact statement.

"I called out to Freda twice, 'Are you there love?'' but she didn't answer me.''

Mr Page suffered a heart attack, rib and spine fractures and a brain bleed as a result of the smash.

The court heard the offender was devastated by his stupidity.
