As anyone who follows me on Twitter will know, I’ve long questioned the point of autonomous vehicles. If anyone knows the answer, feel free to tweet me. But it seems the concept of driverless vehicles is something we’ve all recently had to come to terms with, in a different way.

I refer of course to the lorry driver shortage that has led not only to a rash of empty shelves in your favourite supermarket but also to the delicious irony of people like Leave-backing Lord Wolfson complaining about the government’s fabled post-Brexit points-based immigration policy which he has admitted is an underlying cause.
