CCTV captured the seconds before a young driver hurtled into a parked cement mixer, killing one of his friends.
Footage captured Taylor Hale estimated to be driving his Mazda 3 as fast as 82mph when he used a bus lane to undertake traffic onRoad.
After seeing the unlit cement mixer too late and too fast, Hale slammed into it – killing his 21-year-old friend Mohamud Mohamud.
Hale was advised to say nothing when interviewed, but admitted he had a tendency to show off.
The 23-year-old, of Victoria Parade, Bristol, pleaded guilty to causing death by dangerous driving and causing death when driving while unlicensed on October 4, 2018.

Judge Michael Longman jailed him for four years.
He told Hale: “It was a tragic and needless event caused solely by your bad driving, your undertaking and your excessive speed, all of which were highly dangerous.”
Hale, who stood as sentence was imposed, was banned from driving for five years on his release and told to pass an extended driving test.
Julian Howells, prosecuting, told Bristol CrownHale was driving two passengers, heading for a night in Cardiff, when he joined Fishponds Road and headed towards Eastville at 8.30pm.
After undertaking driver Victoria White, who heard “loud, bassy music” blaring from his car, Hale then zoomed by drivers Libby Hutchinson and Khalid Sipra.
Mr Howells said: “Witnesses heard what sounded like an explosion and saw flyng debris everywhere from the left hand side of the vehicle.
“It had collided with the right side of a parked cement mixer.”
The court heard people including a doctor and nurse stopped and tried to help the injured occupants of the Mazda, the most seriously hurt being Mr Mohamud.
Hale, who was visibly shaken, said he had injured his foot.
Emergency services cut the Mazda open but Mr Mohamud was pronounced dead at 9.06pm having sustained an unsurvivable chest injury.
A police collision investigator estimated the Mazda was travelling at between 76mph to 82mph in the bus lane.
All three occupants were wearing seat belts and some rear-end damage was caused to the cement mixer – the driver of which was fined for not using parking lights at night.
Hale, who had a previous conviction for speeding and two for jumping traffic lights, had previously had his licence revoked after notching up nine penalty points as a young driver.
‘I was showing off’
David Scutt, defending, said his client conceded: “We were going to Cardiff.
“We were in a hurry.
“I was driving too fast.
“I was showing off with and to my friends.”
Mr Scutt said his remorseful client had killed his own friend after the poor driving which resulted in him hitting an unlawful obstruction.
He added: “There is nothing he can do to turn back the clock.
“There is nothing he can do to bring his friend back.
“He recognizes he has imposed an impossible burden on Mr Mohamud’s family.”
Mr Mohamud’s sister, Fatima, gave a moving impact statement in which she said: “Ever since the accident there’s a hole in our life that hasn’t, and never will be filled.
“In my mother’s words Mohamud was a beautiful, precious gift from God that was taken back to its creator.
“Mohamud’s death has affected us in so many ways; physically, mentally and emotionally.
“It is so gut-wrenching and heartbreaking as a sister to watch my younger siblings suffer every day and not be able to do anything.”
