Certain things about Forza are kind of starting to annoy me. The drivatar thing is a cool idea but the way they operate is really dumb it seems. It is hard to drive clean when the other drivers are just all over the place.
It seems like the opponents are just totally unaware of you on the track and won't care if you are coming underneath around a turn, they just hit you. Then in turn, your drivatar starts driving bad in other races.
I am not the best driver, but like 95% of my hits and wrecks are me driving normally and the unaware opponents driving like I am not there.
It is like they tried to make it so similar to how you race, they didn't account for the other cars. For example, I brake really late into turns. Much later than my opponents. But when a car is ahead and of me I don't just plow into them because they brake earlier. However, when I am offline, that is precisely what my drivatar does because it knows I brake late and doesn't seem to account for (or care about) the car in front of it.
