The mother of Oliver Bourton, the McLaren worker killed after his modified Subaru Impreza crashed into an approaching van, said "a part of her died" when she learned of her son's death.

Susan Bourton was speaking after an inquest into how her boy was killed, at Woking Coroner's Court on Friday, December 5.

She was with Oliver's father, Martin, brother James, grandfather Len Morton and girlfriend Rachel.

Oliver, of Sutton, was 22 when he was killed along with his passenger Darren Hayes, 19, from Staines, on January 29 this year.

The court heard that Oliver had travelled past a 35-meter 'body of water' moments before the smash, although there was no evidence either way as to whether the car hit the large puddle either partly, in full, or at all.

The car was then seen to lose control and 'aquaplane' sideways until it hit the van.

After the hearing Mrs Bourton was close to tears as she spoke about her son, a former Glenthorne High School student.

She said: "I just don't want any other family to have to go through what we have gone through.

"Children are the reason we do anything.

"When you are a parent you do anything for your children and now one of those big reasons you do anything has been taken away.

"Part of me died with him.

"He will live with me forever in my heart."

Assistant Coroner Simon Wickens heard how Oliver and his colleague Darren had left the McLaren complex at lunch time.

They were seen by witnesses driving away at an 'above average' speed, with police expert PC Jo Robins, saying he was averaging around 64 miles per hour when he lost control and collided into a white van driven by Terrence Webb.

The van driver told the court he could see the Subaru 'fishtailing' as it came into view and was out of control.

The reaction time between when the van driver, who captured the whole crash on his on-board CCTV, could see the car and the collision was established to be 2.4 seconds.

Another witness, Samir Monroe, said he saw the sports car lose control and appear side on in the wrong lane.

Mr Wickens cleared Mr Webb of any responsibility.

Speaking to the court Mrs Bourton said: "It was a pleasure to be his mother, always.

"We did whatever we could to make his dreams come true."

Susan's sister, and Oliver's aunt, Julie Morton Ford told the Sutton Guardian afterwards: "He is the first thing you think about when you wake up and the last thing you think about when you go to bed."

Father Martin was also upset when he said "I'm down as low as you can possibly go."

He said: "All of our lives have been (affected by this) and we will never be the same again.

"It will never be the same again and that's the (truth) of the matter."

Following the coroner's findings the Bourton family released a statement saying they planned to campaign to 'ensure no further accidents of this nature occur'.

The statement read: "We do not want any other family to have to go through the heartache and misery that our families have had to endure this year and will continue to carry with us for the rest of our lives."

They will be seeking to have the speed limit on the road reduced from 50 to 40 mph.

Darren Hayes' parents Les and Karen also released a statement after the hearing.

It read: "Darren was an amazing son and brother, with a wicked sense of humour.

"He was also extremely kind and thoughtful and was well thought of by most people who met him.

“His death has left a gaping hole in our family, which we will never get over."

Coroner Wilkens concluded that the pair's death had been caused by a road traffic collision.
