Having grown up in Indiana, and having watched a lot of drag racing, and even crewed for a friend drag racing motorcycles, I have not once wondered that, either. I, of course, just assumed it was that way everywhere. “What, your small nowhere town doesn’t have its own drag strip or dirt oval? How odd…”

(And when I say “nowhere”, I mean go look up Bunker Hill, IN as a go-to example. It’s a fine town as far as small towns go, but a long way from any major metro.)

Back when people still watched cable Street Outlaws was Discovery's biggest show for a while. It is an oddly specific thing, but a question I heard a lot about ten years ago. The two places where drag racing are biggest are Oklahoma and Indiana.
