That's certainly an interesting point Rob, but quite often in F1 drivers will be judged on his talent from a previous series. (Although finances seems to play a bigger and bigger part). So I would assume we should look upon the talent as a general she/he did well in a previous series that isn't mentioned in the game. For example in karting he performed well and so on and so fourth. On paper he is a "talented" driver.
But like I have said before. Prost and Co couldn't touch Senna in the rain no matter how much they drove in it.
Senna came to Europe from Brazil with very little experience of wet conditions where as Prost had it from a very early stage in karting, being from Europe.
With the YDA everyone will have tallent 20's with training up to 20's in the attributes... Attribute capping randomly would give driver a personality..
Every driver has their limits.
