An interesting challenge, which raises the question: what music best accompanies long stretches of driving? While there are doubtless some albums which fit the bill, they are many individual songs which have always enhanced the driving experience (first on my list, "No Love Lost" by Joy Division, though 'She's Lost Control', with its constant drumbeat, celebrated in Winterbottom's "24 Hour Party People", also does the trick). Since Stuart and Marc are racing enthusiasts, I imagine they will both have some interesting suggestions here. Well done, Gavin.

Thinking caps on.
