Most people don't but that's an overly broad generalization.
I raced Spec Miata in its early days (2000-2010) and it was possible (and I did) to keep a moderately competitive Spec Miata still street legal. I didn't have space for a trailer so had to drive it to the track.
Ha! I cut my teeth on Spec RX-7. I drove it to the track for a season and it was a terrible idea. The car was nominally legal (catalyst in place, full exhaust). But it was loud AF, the rollcage was dangerous on the street, and getting 4 race wheels in the back with a jack, tools, tent, etc was an endeavor.
