I know, in the US you are more attracted to Nascar, Indy, Drag racing, Drift maybe, because they're everywhere.
Personally, I don't find any pleasure in watching cars on a circuit, doing the same stuff over and over again, on the same surface. Rallying is more complex, 2-3-4 days, about 12-14 hours per day to stay focused as a pilot and copilot, different surfaces, different altitudes, different weather conditions, it's way more thrilling and intense than any other motorsport.
But rallying lost some of its fame, and now it's struggling to gain it back.
