When you show up for a regional you know a national driver may be hard to beat.
And with a majors race you may find a driver that may not have the skill level you think is required.
What do think if a driver performs and gets a podium in regional (top whatever), their a nationa/majorl driver.
And you need a min finish position to run majors or run a majors regional class
So for a regional race, you'd have national drivers race in their class and regional class
and for majors you have majors and may have regional drivers entered in another class.
Not looking for warm fuzzy everyone gets a trophy but what level your at you get a chance to win and more turn out.
