But for me (a non-fan) the only thing I think would be more boring than watching cars run in circles making left turns for three hours would be watching left turns being made from within the cars for three hours.
Well, when you boil down any spectator sport or event to its most simple definition, it can sound boring.Basketball:
"I don't want to watch a bunch of tall people throwing a ball through a hoop for two and half hours."Rock concert:
"I don't want to see some guys strumming on guitars and banging on drums for two hours."Ballet:
"I don't want to watch a bunch of tiny women prancing around on a stage for three hours."
Of course, each of these events, along with auto racing, has a great deal more complexity and nuance that these oversimplifications.
