Keira Ridler, of Hampson Avenue, Wrexham, appeared at Mold Crown Court for sentencing on Thursday morning.
The 26-year-old, formerly of Marlborough Road, Ellesmere Port, admitted two counts of causing serious injury by dangerous driving at an earlier hearing.
Prosecuting Ryan Rothwell told the court that on the evening of September 19, 2021, a car meeting for motoring enthusiasts was held at Cheshire Oaks.
Up to 200 vehicles were present.
Later in the evening, an unknown individual advertised on social media “Mexico” – a term from the American car scene for an illegal meeting where participants would race or otherwise drive illegally.
The place for the second meeting of the cars was the Manor Industrial Estate in Flint.
A number of vehicles took part and more than 100 pedestrians gathered on the pavements around the site.
CCTV footage showed what happened during the evening, with a line of vehicles speeding up and down the straight, 30mph road.
Ridler, in his Nissan Juke, was seen going up and down – not racing other vehicles, but definitely speeding.
The first victim, Ellie Blower, was in a VW Golf which was slowly exiting the T-junction.
Ridler collided with the Golf despite attempting evasive action.
Analysis of CCTV footage showed she was traveling somewhere between 50 and 115mph; but it was probably 60 to 70 mph at the point of impact.
The court heard the plea, which the prosecution accepted, said Ridler was traveling towards the lower end of that speed scale.
The other victim, Christopher Rakeshaw, was on the edge of his phone at the time.
He remembered hearing the screeching of tires and then being hit.
Mr. Rakeshaw reached the floor not far from where he stood.
He fell into a coma for a week and a half and suffered “catastrophic” injuries.
After months in hospital, it was confirmed that the now 26-year-old is a quadriplegic – having lost the ability to use both his arms and legs.
He now lives in a converted bungalow with a team of six carers providing the round-the-clock care he will likely need for the rest of his life.
The court heard that in the immediate aftermath he “begged people in the crowd to kill him” because he did not want to live with the injuries he realized he had sustained.
Ms Blower suffered multiple injuries in the accident, including a broken ankle, leg, wrist and severe abdominal bruising.
Eight months after the incident, she was still unable to bear weight on her ankle and needed anesthetic injections to manage the pain up to 11 months after the accident.
Ridler herself suffered a whiplash and dislocated collarbone in the incident, and her passenger suffered a broken wrist.
In interview, the defendant admitted that she was traveling over 30 mph, but not significantly so.
She denied “speeding up and going down the road” and initially denied that her behavior amounted to dangerous driving.
She initially accused the VW Golf driver of the collision.
Richard Dawson, defending, told the court: “This was clearly a tragic case which had disastrous consequences for everyone involved in the events of that night.
“Obviously our condolences go out to the victims who suffered serious injuries, particularly Mr Rakeshaw.
“Honestly, you can’t imagine a more serious injury that didn’t lead to death.
“This is a lady of previous good character with an otherwise clean driving record.
“The third anniversary of the crash is fast approaching, and for the young lady hanging over it, events and life have moved on – and her pregnancy is the result.
“Whatever sentence this court may ultimately pass will pale in comparison to being separated from her young child, now just 15 months old.”
He said his client attended the rally because of her “passion for cars”.
“All of them took part in what we have to accept was an illegal car meeting,” he said.
“Mrs. Ridler was in charge of that meeting.
“This was in every sense an out of character incident for her as her record shows she is a typically cautious driver.
“She is deeply sorry and wants to apologize for everything that happened.
Judge Niclas Parry told Ridler: “Your aim was to show off and attract attention.
“That’s what you did, you drove up and down the road at 30 mph way, way over the speed limit.
“There was an unavoidable collision and the consequences can only be described as catastrophic.”
The judge imposed a total sentence of 20 months and then held a trial in court to consider whether that period could be suspended.
Ridler sobbed in the dock as he concluded that the case was simply too serious and prison would have to start immediately.
He was banned from driving for two years and 10 months.
