So, one minor nitpick, but this goes for almost all racing games out there.
This is the Driver's Championship results for the 2013 WTCC season:
First, you have to ignore Muller, because he is some sort of supernatural being, and took 1st seven times, but he also came in 4th, 5th, 7th, and retired.
More importantly, looking at Tarquini, he only stood on the podium a third of all his races, retired three times, didn't even race once, and still came in second. Nash was only there in a fifth of his races.
This is how a championship standing is supposed to look. Yes, you have gods like Muller, but even gods end up coming in 5th place a few times. Instead, Forza Horizon 2 (and, really, every racing game out there) has it where AI1 comes in 1st in every race, AI2 comes in second, and so on. This means that if you place second in every race of a championship, what should be an amazing feat, you're still going to lose on points to the one guy who always comes in first.
Also, I hate that the AI doesn't need to hit the checkpoints. Just frustrating to see that you're bound by different rules than every other car on the track.
