I feel the the concept of competing for your nation have potential, but the mathematiscs need to be simplyfied.
My suggestions:
- 1 car from these classes: Rally2, Rally3, Rally4, Rally5
- In rally2 and 3; free choice of drivers
- In Rally4; must have a female driver.
- Rally5; car must have a junior driver under 20 years.
ClassWinner gets 1 point, 2nd 2 points and so on.
Lowest score in 3 of 4 classes take glory.
Maybe Rally needs to move venue.
Sponsors need to pay for transport of cars and crew to rally site.
Feel free to comment with your ideas.
