Sorry guys but if you drive like a human I think we have some of the best AI ever shipped in a game. It's impossible to please everyone and yes they do get a bit aggressive above 80% but at 80-85% I'm having a wonderful time with them.
Respect where they are on the track. Don't assume they're going to just give way to you because you have a bumper inside them.
And yes they are occasionally fast off track but the alternative is they bash you or give up as it's normally YOU pushing them off track. The solution we have reached is the most appropriate for fun racing as I see it.
