Long evenings spent at motorsport events offer ample chance for hypothetical chat. One of my favourite examples concerns a former Autosport journalist and a British motor racing commentator of fine repute.
They argue over the outcome of building a time machine and transporting Jim Clark - in his pomp - forward to the modern era of Formula 1, while sending an average grand prix driver of the current day back to Clark's time.
The commentator argues Clark would be every bit as good in the modern era as he was in his day, and that the average modern driver would struggle to muster the requisite courage to compete successfully during motor racing's most dangerous period.
