That article has a quote and a photo showing it went down the slope....
A Devon and Cornwall Police spokesperson wrote on social media: "The driver of this vehicle ended up obstructing rail tracks at Carbis Bay having left the road and down an embankment.
Yup, I'd initially thought the driver would have come from something called Boskerris Road above the line, overshot the junction and through the fence there but... they appear to have come *up* the road from the bay, ignored the bend at the bridge, straight on, through the fence there and down the embankment.
The photo also shows little to no marks on the road so no slamming on of the brakes - and also possibly airborne as the fence was far more of a casualty than the edge of the cutting which has only minor damage. Oh and for good measure what may have been a fence post has impacted the bonnet and restyled the Mercedes front end as a BMW.
Another unexpected detail, the airbags do not appear to have been triggered. Or perhaps that vehicle has a mode that deploys them as parachutes or cushions for landing.
