From time to time, when I stray from talking about motorcycle racing to share something political on Twitter, I am told by some random Twitter user to "stick to bikes". What they mean, of course, is that I should not share political opinions or articles they do not agree with, but that's a different question.
Talking about politics is, of course, still "sticking to bikes". Circuits have to be built somewhere. That requires obtaining permission to start construction from some level of government. They have to be funded, with money often being either supplied or backed by some level of government. They need roads to access them: built by government.
