This is the astonishing moment a couple are filmed having sex at the wheel of a car while driving at 70mph.

The passenger in the vehicle passing them was so shocked he got his mobile out and recorded them in the throes of the passion.

The bespectacled mystery man with the woman bouncing up and down on his lap appeared to be just about managing to keep his eye on the road in front of him over his lover’s shoulder as he left one hand on the steering wheel to avoid crashing and ran his other hand through her hair, reports the Metro.

Instead of slowing down or pulling over when he realised he was being filmed, he reacted by sticking the middle finger up on his left hand as the other driver passed.

The uninhibited pair even appeared to have turned their hazard lights on by accident as they made love partly-dressed, making their show impossible to be missed. Local reports said the car was doing around 70mph.

The shocking incident happened near Yala in the province of Jujuy in north-west Argentina on National Route 9, a major road which links the capital Buenos Aires to the country’s border with Bolivia and crosses seven provinces.

Argentina has one of the highest traffic-related death rates in the world, with around 22 people dying every day in road traffic accidents.

Argentina topped a road traffic death league of shame released two years ago by the International Transport Forum, showing more than 5,000 deaths per year, although the situation at the time was said to be improving.

Parts of Route 9 have been branded among the most dangerous in the country, with animals on the road being a problem as well as the number of people who still drink-drive.

Ten vehicles including five lorries collided on the road last month during a dust storm, causing one death. Local newspaper Notinor Jujuy, which first published the video, said: ‘A reader filmed this foolish behaviour by a driver who was on National Route 9 near Yala this weekend.

 ‘Roads in Jujuy have a high accident rate and this type of behaviour definitely doesn’t help.’ Police are understood to have been sent the footage so they can investigate, although the driver’s numberplate doesn’t appear.

Enraged local Vanina Nancy said in a direct message to the couple on social media: ‘It would be your problem if you crashed but why put the lives of innocent people in danger. ‘I hope your family recognise you in the video.’

May Villalba added: ‘People with no brains. Maybe these idiots don’t give a damn about their own lives but there are people on this road who do and make sure they do everything right from the moment they put their seatbelts on.’

Last month a man was arrested in the States after crashing a car naked while allegedly having sex with a woman whose baby was strapped in the back seat.

The couple sustained multiple injuries when the vehicle slammed into a tree on a road in Washington State. The three-month-old child, properly restrained in a car seat in the back, was unharmed.
