Hi a two part suggestion that effects both drivers and car.
Part one Drivers Morale
Would be better if it wasn't trainable, and instead have Plus & Minus points based on driver performance in the race.
Plus points for finishing in the points
Plus points for gaining positions in the race
Plus points for reaching team objective
Minus points for failing team objective
Minus points for losing positions in the race
Minus points for not finishing a race (should never happen but I see it does sometimes)
Part two Car Setup
I would like to see the car setup change based on driver experience level instead of driving ability ratings.
Most new drivers start with 4 or 5 experience, the closer they get to 20 points the better their setup will get.
