A Deliveroo cyclist was spotted biking in the outside lane of a busy motorway after his sat nav took him on the "wrong road".
Railway worker Scott Inglis, 32, filmed the moment he saw the cyclist on the M8 near junction 16 for George Square in Glasgow on Saturday July 3 at 4.12pm.
The unidentified man was cycling in the third lane that is coned off for roadworks, and he crossed two busy lanes to get onto the 50mph section of the motorway.
He shouted at the cyclist: "What ye dain [doing], it's a motorway you are on - you're off your f****** heid."
The cyclist then yelled back: "Wrong road."
"Wrong road, absolutely, f****** maniac," Scott replied, while laughing.
He later shared the clip online with the caption: "Wrong road? Think you could be right mate."
