A beautician who survived a horror crash on the A40 said the driver swerved to avoid an animal.
Zamarod Arif, 26, said it felt like she was "in a Tsunami" when the 4x4 she was travelling in flipped onto a train track.
Zamarod's best friend Yagmur Ozden died in the smash, which took place near Park Royal tube station in west London on Monday.
The driver of the Range Rover, Rida Al Mousawi, was reportedly driving at up to 100mph in the early hours of Monday morning.
He is now said to be in critical condition in hospital, with another man also injured after the 4x4 smashed into his parked Tesla.
Shocking images showed the wreck of the Range Rover sitting on the Piccadilly Line after it veered off the A40 and shot through a Tesla Centre car park.
Zamarod said both she and Yagmur were urging Rida, 24, to stop speeding in the moments before the crash.
She told Mail Online: "Yagmur was also telling him to slow down. She had a previous bad experience and didn't like going fast. We were both afraid.
"I looked over at Rida and touched his arm to say slow down. He looked me in the eye and said it will be cool.
"Just then Yag shouted out that there was something in the road. I don't know what it was, a cat, or another animal.
"Rida went to the side, and once that happened we just took off."
Zamarod, who was sat in the front passenger seat, told Mail Online that she was the only one in the car wearing a seatbelt.
She was conscious for the entirety of the ordeal and said she felt "every tumble" during the crash.
She compared the experience to a scene from the 2012 film The Impossible when one of the characters is hit "left, right and centre" by a Tsunami.
Zamarod said she was thrown around the inside of the Range Rover during the crash.
Meanwhile, her friend Yagmur and the driver Rida were launched out of the vehicle, she said.
Zamarod told Mail Online that she urged the pair to put their seatbelts on before the crash, however they did not listen.
The beautician suffered a broken leg and broken arm in the crash but miraculously avoided sustaining any serious injuries.
Rida already knew Yagmur and Zamarod from previous social occasions and met them again at the popular Wish Lounge nightspot just before the crash.
He agreed to drive the pair back to his home so they could get charging cables for Yagmur's car after she discovered she had a flat battery.
Zamarod said she could see Rida "alive and breathing" on the station platform in the aftermath of the crash.
She shouted out to him but the jewellery store manager did not reply, she said.

Zamarod could not see Yagmur and later found out she had died.
Yagmur's family described her as an angel who could cheer up even the saddest person.
Her family, who were overseas at the time of the crash, said: "She had an amazing bond with her daughter and her daughter will always cherish those moments she had with her mum."
