An gullible lorry motorist managed to drag a car for miles on the motorway but realising.
A video showed the bizarre occurrence that happened on the I-15 freeway, in California, on Wednesday.
The lorry motorist only detected there was a problem after other vehicles started to beep their horns while they were passing.
Eventually a motorist slowed down in front of the lorry in sequence to make it stop.
Brian Steimke, who filmed the clip, confronted the lorry motorist by asking him: ‘Why were you pushing so far?’
The confused man responded: ‘So far?’
Mr Steimke added: ‘The man was under your car.’
To which the motorist said: ‘I didn’t know it.’
The motorist of the smaller 1996 Nissan Maxima car was not seriously harmed but his car suffered a lot of repairs after being dragged for some-more than 4 miles.
California Highway Patrol officials reliable the crash was not being treated as a rapist incident.
