While idling through a routine piece in The Times about US authorities urging car makers to get on and build connected cars – for safety's sake – I came across a charmingly jingoistic quote from one Anthony Foxx, the US transportation secretary.

It's the sort of casual nonsense we hear from our own politicians, but because it was in a sense directed against 'us', I suddenly saw how unhelpful it was.

You don't need to hear everything Foxx said, just the last bit: "This technology will play a key role in improving the way people get where they need to go, while ensuring that the US remains the leader in the global automotive industry." It was that last few words that caused me to choke on my Weetabix.

The US auto industry has not been "the leader in the global automotive industry" since the great works of Alfred P Sloan (GM) and Henry Ford lost currency before the war. While car ownership in the developed world was building up, it was only to be expected that the world's biggest market should have been able to do most things first, best and in biggest volume.

But even back then, the most accomplished manufacturers of Britain, France, Italy and Germany built cars of equal capability, engineering sophistication and style. And more enduring brand appeal. Having a vast market soon came to look like the enemy of excellence and to an extent it remains so.
