Shocking footage captured the moment a woman attempted to solve a Rubik's Cube - while driving along a busy motorway.

A video shows the motorist driving along the M61 near Manchester at rush hour, completely engrossed in the puzzle.

Shocked onlooker Macauley Stephens spotted the woman and said she carried on for several miles, using both hands to complete the Rubik's Cube - and was oblivious she was being filmed.

But incredibly, after being spotted fiddling with the 3D puzzle – invented by Hungarian sculptor and professor of architecture Erno Rubik – the driver continued to play with it.

Mr Stephens filmed the incident as he travelled from Manchester to Bolton.

The 21-year-old said: 'When I spotted the woman I honestly couldn't believe what I was seeing, I was shocked more than anything.

'How she could concentrate while driving on a busy motorway at peak time beggars belief.'

Mr Stephens added: 'She saw me looking at her - as you can see in the clip - and she wasn't even affected at all. She just carried on for several more miles doing the puzzle.'

After capturing the footage on his mobile phone Mr Stephens tweeted it to police, but said he hasn't heard anything from the force.
