The Final Jeopardy question tonight was “Its name refers to safety efforts that currently restrict cylinder capacity & prohibit supercharging”

The correct answer: What is Formula One?

Can someone explain this to me? It doesn’t really make sense. The Formula part of the name just means that all the cars are built to the same rule set and the 1 comes from the grade of the tracks that they race on. How confused were the Jeopardy people when they made this question?
