How good is the AI/CPU?

If you complete practice and setup a good strategy, how good is the AI in thisvgame if you don't attend the race?

For example, will the AI manage tire temperatures and use boost wisely?

Do your guys in Pro or Elite ever prefer to just let the AI race for you?

Lastly, can I attend my own race as a viewer and not manage? Just watch?

Honestly... It's not that great, but there are quite a few Offline leagues around where everybody likes to play that way. You are actually forbidden to join races in there.

The Ai is terrible. If you are thinking of using it right now youre probably safe given how you dominate your races, but when you have any competition, not turning up to a race is a guaranteed loss.

This helps! There are usually from 3 to 6 other LIVE players in my races thus far. 4 in the last race. So will probably attend races when possible. 

thx!
