Journalists too often forget that motor shows aren’t actually put on for their benefit. We’re the ones who are first into the halls and pay nothing for the privilege, and we’re the ones who are almost entirely oblivious to the paying public who’ll come in their tens of thousands for days and weeks to come.

Many will be seriously considering the one thing that hardly ever crosses a car journalist’s mind: which new car should they buy?

And yet if it doesn’t sound too bigheaded, we do have a role to play. The show-going public may number tens of thousands, between the few thousand of us hacks who show up, but our words reach not tens of thousands but millions around the world.

Yet in Beijing that fact appears not yet to have fully registered. It still has the feel of a local trade show that has yet to realise either how large it has become or how important on the world stage it is now perceived to be.

At the show’s exit, even the most relentlessly cheerful of journos owned up to having had a trying day and it wasn’t the smog they complained about; unlike two years ago it wasn’t so bad that it was actually inside the buildings. Nor was it the traffic, which caused every person I spoke to at the show to abandon their transport to the show and walk the last kilometre. That was inconvenient but not unexpected.
