My unpopular motorsport opinion? Whenever I hear about a neat, new race car, I always think to myself, "Could this car come to Gran Turismo?" I don't even really watch motorsport, and I don't even watch the FIAGTCs anymore. I'd much rather try participating myself, especially in Gran Turismo. There's even a notable circuit in my state, about two hours from me, where IMSA races every year - Lime Rock Park. So I'm thinking that one of these days, I'll try karting there.
Otherwise, I don't really care about some glorified trust fund babies who were lucky enough to be born into super-wealthy families, and who usually start racing well before they hit puberty. There's only one motorsports story I could find myself seriously emotionally invested in: mine.
EDIT: Here's another one. I cannot understand for the life of me why people watch oval racing. As for the Indy 500, I'd much rather they use the infield course. I get that the ovals can vary a lot in banking, and even general shape, like an actual oval versus a tri-oval, and so on. But I just can't understand why would anyone want to watch NASCAR over other American series like those from IMSA, especially with recent memes regarding the current president not exactly helping the stereotype that NASCAR fans are uneducated hicks. Oh well, at least there's Matt "Empty Box" Orr. I respect Indycar more than NASCAR - at least they go for more than just ovals all the time. I might be more inclined to watch NASCAR if they actually went back to their roots, and let the "S" actually stand for "stock," complete with homologation specials, and raced at more than just ovals. But like I said earlier in this post, that's assuming I'd be inclined to watch motorsports at all. Maybe I'd prefer it to physically attend a local race, like the IMSA round at Lime Rock.
