Just back from seeing a touring production of Chitty Chitty Bang Bang. A bizarre enough title in itself - and in this day and age a surprisingly odd choice of stage musical.

After all, here is a car with a huge V12, high Co2, uncatalysed engine which doesn’t just pollute the road, but also the seas and the skies.

Yet every time that Chitty spreads its wings or inflates its hover skirt, there are whoops of delight, not just from the kiddies, but the grown ups too.

So despite children being forced to watch Al Gore’s video nasty and absorb a constant diatribe from the right-on media that cars are to blame for everything, it seems we still love Chitty.

And quite right too, after all he helps free all those children kept prisoner in Vulgaria, hunts down the child catcher like a vigilante, overthrows the wicked Royal family and establishes a republican democracy.
