Sentencing, the judge said Tavener had driven at excessive speed while trying to overtake another vehicle in a 20mph zone at night, “with cannabis in your system and using a phone”.
He told the defendant: “The victim was a vulnerable pedestrian – you were on your phone, it was a car with no insurance. You said you were a rear passenger instead of the driver. The passenger’s post-incident conduct was as disgraceful as yours.
“You abandoned the car at the scene, after reversing, presumably to try to leave, dragging little Mayar. You walked off calling for your girlfriend.
“The callous way in which you walked away from the mayhem was sickening to watch. You blamed a phantom driver.”
The court heard that while overtaking, the front of Tavener’s vehicle came into contact with the rear of the other, which is how he ended up mounting the pavement, and hitting the pedestrians.
It was dashcam footage from that other vehicle that was reviewed by the judge before sentencing.
There were audible gasps as the footage was played in court on Friday.
At the same hearing in which he was sentenced to 46 months in prison for the motoring offences, Tavener, for unrelated crimes, was given an additional 18-month jail term in relation to an assault, with three months to run concurrently for battering, bringing his total sentence on Friday to 64 months.
He was also banned from driving for six years.
