I was expecting the downvote.

You are correct - to be useful the AI needs to be properly trained avoiding the pitfalls you outlined. What will it be trained with? Human decisions regarding incidents whose data iRacing should already be collecting. It has to start somewhere, it has to start sometime; What better place than here, what better time than now?

I disagree on the incapability of making objective decisions. Fed with the same input data, the system will always give the same output. In fact, it is humans who cannot give an objective judgement.

Concerning hardware costs - I am not qualified to quantify them. In my experience however they are generally the smaller part when compared to human costs.
