Hi there, been a long time manager in this game and one thing that has bothered me about the design in it's current iteration is the information it has to definely tell people how much better their car is to the attribute.
Instead of showing a bar and setting it to somewhere along the line, could this instead be changed to showing your ranking in the league in a certain attribute? Obviously the X with first having y being excluded.
Acceleration: 4th (Some small improvements possible) (170 with 1st being 200)
Braking: 12th (some improvements possible) (100 with 1st being 150)
Downforce: 8th (some small improvements possible) (67 with first being 88)
Fuel Economy: 11th (A lot of Improvements possible) (45 with first being 160)
~Etc
I feel it gives away too much information at the moment and doesn't allow enough ambiguity.
