The terrifying moment a car flipped 360 degrees in the air after it was sent veering up a grass verge by another motorist has been captured on dash cam.
The woman who witnessed the crash was driving past junction 14 of the M4 in Berkshire, when she saw a black Jaguar saloon swerve suddenly across the road.
As the driver lost control of his flash car, a motorist on his left was forced to veer out of the way and inadvertently sent himself careering towards a grassy embankment.
The car hit the verge at 50mph and flew up into the air, tumbling over, before landing with a crash.
Mitch, who did not want to give her second name, told MailOnline: ‘After pulling over the guy in the Jaguar got out and went to apologise to the guy in the other car.
‘Thankfully, he had managed to crawl out. I then overheard him saying ”you nearly killed me”.

The M4, which runs between London and South Wales, is one of the most congested motorways in the country – often due to crashes.
On Wednesday a woman was taken to hospital after a collision near junction 45 at Ynysforgan, Wales.
