Not sure if either I found a bug or it's just how it should work in this game, but I need some opinions and answers about this.
Some time ago I had a very promising driver, got it at lvl 11 and kept winning a good bunch of races with him. I was thinking back then, if I bring this driver to max lvl, he will wipe everyone's arses! So, after finishing training the most important areas, I started focusing on Mental. Months later, I realized my driver started struggling getting on top positions (even with a well developed car). Maybe the age was the problem, maybe by getting older actual performance starts to fall down (the driver was 28-29 if i recall right)
Now I'm in a 2-car league. I have a lvl 17 driver (following the same training program of the driver above) and a lvl 13 driver which i just signed. Both have almost same age. I was expecting the newcomer to be slower, but he's instead constantly beating the lvl 17 driver. Another big question mark on this.
Then, just for curiosity, I started to take a look at top players' drivers, it never hurts watching how pro players manage to win races, and I surprisingly found out most of the drivers had about same stats: lvl 14 and maxed out on Attacking, Defending, Physical and Speed. Some drivers had hundreds and hundreds of races and they were still lvl 14.
After a while I eventually realised that my efforts in bringing drivers to max lvl were useless, as it seems to make drivers slower than before (even if they're kinda young)... Maybe mental training is the problem? Are less-Mental trained drivers actually faster? Is lvl 14 (with speed, attacking, defending and physical stats maxed out) the "perfect" lvl for a driver? Training on a lvl above 14 does actually give any benefits for the driver?
