There's a certain criticism that can be directed at motorsport that's quite hard to argue against. The point that, really, racing ultimately boils down to cars going around in a series of circles in a seemingly never-ending quest to see who has won the motorsport, with hundreds of events every year, each more climactic than the last. There's never a really definitive winner, the cycle begins again every season. Variations of the same point can really be levelled at any sport.
But while that argument may have a core of truth, it's the combination of everything that goes around the racing that adds up to why people follow motorsport. The technology, the spectacle, the money, the personalities, the danger, the myths, the glamour, the adrenaline, the humanity and, of course, the venues.
In a series such as Formula 1, the calendar, by and large given the number of new tracks that have held races in recent years, is still made up of the same core events. These have become icons and would be sorely missed. Think Monza, Suzuka, Monaco.
