A combination of jet lag, tradition and technology means that I’m writing this column at an absurdly unsociable hour from my temporary office-cum-studio on one of the best-known driving streets in the most notorious car city on the planet. I’m jet lagged because I’ve just travelled from China, which is eight hours ahead of the UK, to Los Angeles which is eight hours behind. So it’s little wonder that my body clock is more troubled than a Ford corporate accountant and I’m wide awake at 3.30am, penning these words on the eve of the LA Auto Show.
