An unconscious man drove for more than 15 miles thanks to his car’s cruise control and Lane Assist.

Motorists on the E314 heading towards Leuven, Belgium had noticed a driver slumped behind the wheel of his Renault Clio at around 9am on Sunday, 14th August.

They called the emergency services and police teams arrived on the scene from nearby Hasselt to guide the vehicle and bring it to a stop.

When police approached the car – which had been spotted in Houthalen and Heusden-Zolder – they realised the driver was unconscious.

Witnesses said the vehicle had been drifting from left to right in the lane while travelling at a steady speed.

It is believed the car’s Lane Assist and cruise control were engaged.

The Lane Assist would have returned the car to the middle of the lane every time it began to meander off course.

And the cruise control would have kept the car moving at a constant rate.

Police attempted to slow the vehicle down by pulling up in front of it.

It is believed the car scraped a safety barrier near Halen, bringing it to a stop on the verge.

An ambulance was called for the driver – a 41-year-old man from Hasselt – who was still passed out.

In hospital, he was given alcohol and drugs tests, the results of which are still unknown.

Reports said he had started his journey in Genk and had travelled for at least 25 kilometres unconscious.
