It's a beautiful day in West Sussex, although from an early hour the bucolic calm has been punctuated by the sound of race-tuned internal combustion engines.

I like to think I've made my contribution to the symphony by driving our McLaren MP4-12C down to Goodwood. It's fair to say I've had worse assignments. Yesterday evening I enjoyed a gentle and traffic-free cruise down from Middlesex to an overnight halt in Midhurst. It was my first drive in our Woking-bred supercar, because unsurprisingly the key fob is always in high demand in our office.
