My word you must have some low standards if you think the AI in pCars is amazing... on max difficulty its not a challenge, the AI are so dumb as well. The physics are simcade at best, some of the cars are better than others (GT3 and GT4 cars) but some are just appalling, the road cars are particularly dreadful. I hope F1 2015 is better in every regard but whilst i expect an improvement on previous versions i can't help but be skeptical about it. If pCars is the benchmark then the benchmark is very low. If you want good physics then play rFactor 2, Asseto Corsa, Netkar Pro, iRacing or game stock car pro. Don't ever expect great physics from a game where the primary userbase will using joypads.
