This is the terrifying moment a driver sent on the wrong road by his car's satnav realises he is trapped in a frozen Antarctic landscape known as the 'World's Edge'.

Computer expert Thiago Crevelloni, 38, had been driving through remote southern Patagonia in Argentina when his GPS suggested a shortcut.

Unknown to Thiago it had sent him on a little used B road through one of the most hostile landscapes on earth on the edge of Antarctica.

Chilling dashcam footage from 10th May shows Thiago trying to navigate a total white-out landscape with thick snow and ice covering the road.

As he inches forward in near-zero visibility he hits a snowdrift burying his car in ice and Thiago can be heard groaning: "Ah. No!"

Now Thiago has told how he thought he would die when, with no way back or forward by car, and no phone signal he got out and walked for hours back to a main road hoping to find shelter.

He said: "I'd been moving forward, but it started to snow a lot and I realised that I hadn’t seen another car in the last few miles."

Thiago, from Brazil, added: "I thought I was going to freeze to death there. My face was burning, the wind was very strong.

"I started to feel sick, disoriented. After about five hours of walking, I fell to the ground. I lay there in the snow trying to get my strength back.

"I asked God for strength. Then I stood up and walked a few more miles."

By an astonishing stroke of luck, as he stumbled forward he saw a light in the distance which turned out to be a police patrol car, local media reported on 21st May.

Thiago said: "I thought I was hallucinating, but it was a Santa Cruz police car. I cried with emotion. I thought I was going to die out there."

A second scene from a police dashcam shows Thiago approaching the car with his phone torch turned on to signal the officers.

Frozen to the bone, they wrap him up in a snow suit before driving him to the nearest hotel.

The next day Thiago hired a breakdown truck to collect his car and continued his journey to El Calafate, where he planned to work for two months as a digital nomad.

It was only then he realised that the owner of the lodge he was using had raised the alarm when he did not turn up.

Police had been searching for him on the wrong road when he stumbled into the headlights by chance.

Thiago said: "If it wasn’t for her, I don’t know what would have happened.

"Today I am fine, I am calm, I am saved and I can be telling this story.”
