Not a motorhome Heinz, but an SUV.
There is already another thread about this - from the online Daily Mail - though they called it a vintage car (or some such), where it was actually a recent (2018?) car.
It would seem the driver was looking at his satnav approaching a roundabout where traffic had stopped. When he looked up he was too close and travelling too fast to stop. I say seem as that is the story in the Daily Wail (nickname for that particular newspaper).
They describe it as a
Classic British sports car Graham, which is refreshingly accurate given typical press coverage of such.
