This belief of mine also applies to Formula-One: I must be one of the few in-betweeners to follow the sport. People seem to either love it or hate it, there are very few casual followers as far as I know (unless they're faking an interest to seem trendy, which also seems to happen a lot in F-1).
My interest in the fortnightly race is limited to watching the beginning of each race (whenever I can) and the last few laps: for a person like me who likes to maintain only a casual acquaintance with the sport, these two are the points in the race that may offer higher chances of excitement. This is of course not always true, but as I'm not into cars, the technical aspects don't interest me. It is the competitiveness that interests me. I do remember one Grand Prix (Australian perhaps? It was in 1999) where Rubens Barrichello won a very intriguing race which was rain-affected: it was very riveting even for a person like me.
My introduction to the world of F-1 came from endless re-runs of old Monaco GPs that DD used to fill space in the Metro channel pre-1995 years. The actual micro-interest stemmed from some of my friends; Harish, Sujay, Gaurav et al used to bring F-1 discussions to the inevitable pre-BC quiz gatherings. This and some F-1 questions in quizzes sparked off a more regular viewing of Race Day. I still don't understand much of the technical stuff (people like Sumeet would drool over the technicalities), but it helps that F-1 is a continuously flowing game like football where the commentary doesn't stop for every moment of play (unlike cricket or tennis which follow a discrete format); the easy-to-follow non-stop commentary has helped me to keep staring as the riders make their seemingly unending trips around the chicanes and corners, with stewards flashing their flags at them: the amount of information overload with minute durations allowed for comprehension that these drivers have to account for is quite a remarkable aspect of this sport.
I cannot hold a conversation on F-1 racing, but I sure can listen to one without being too baffled. All that talk about monotony hasn't scared me off, at any rate.
