Driver Talent, Experience, Knowledge & Morale

Would it be possible to have them more dynamic/live based on race/season performances.
I don't think any of them should be trainable, the drivers stats should change on their own at their own pace depend on results each season.

Have a progression bar maybe below Experience & Knowledge.

A new kid on the block might have low talent, experience & knowledge, but his morale is through the roof because he is getting a chance to drive.
As he gets to grips with the car and has some good finishes his talent level might increase, of course if he is in his second season he will have more knowledge and understanding of tracks, allowing him to be that little bit better also.
Therefore any more gains in talent should not come until his experience level has gone up after completing his second full season.

On the flip side if he is not performing well his morale will take a knock, slowing his progress in leveling up his knowledge.
If he cant gain knowledge the knock on effect is he's not gaining experience because he isn't learning as much that season & his talent levels are staying low.

Talent - defines the drivers level not his speed. (Stars & Level)
Experience - increases speed
Knowledge - increases experience
Morale - defines speed and the amount of knowledge gained in a race/season.

Resulting in a low level driver growing up and becoming an legend in the game or a flop that no one is willing to take on.

Thats a double edged sword, some drivers plateau at some point in their racing careers, for example Oliver Rowland or Alex Lynn, they have shown a lot of speed and talent coming up the ranks but have been stopped cold in GP2 even though they did nothing wrong.

Some drivers never have the talent even though they come through the ladder, they are just not as quick as others, Heikki Kovalainen and Giancarlo Fisichella are two examples when paired with Fernando Alonso and Lewis Hamilton, neither of them were ever as quick as their teammates in equal machinery and they do show occasionally flashes of speed and brilliance but most of the rest of the time they are firmly in their teammates shadows. Again doing nothing wrong.

Morale and Experience can only get someone so far in motorsport, but i think the talent rating should be a little more random, however a useful addition would be a better talent scout that can find real talent out of the other drivers with a greater chance of the randomness being halved and the talent rating being above a certain minimum level so a guaranteed reasonable driver or a top end driver.

I don't think comparing two drivers is fair unless the drivers are equal age, height and weight to being with.

It not about vital statistics of a driver, it's about what goes on inside the mind of a driver, how brave some are, how hard someone pushes and the risks they will take on track and so on. Giancarlo and Heikki are solid drivers in their time, but neither of them could hold a candle to Fernando or Lewis.

Some are just more inclined to push the limits and others are more about staying within their skills. it's the way some are, also drivers have different racing styles which have advantages and disadvantages.

That would put the cat among the pigeons, if igp was to hide driver stats all we can see is their name, birth date, age height, weight and teams they been in, in training we could be working away at something they have already maxed out wasting our time in training lol

second that!
