In real life it isn't that easy to combat understeer, a majority of novices struggle with it in real life high performance, cars come that way and you have to apply some weight transfers to drive out of exits the way old GTS made it too easy to do. It was over simplified I think acceptable for teaching and exposing gamers to it. In real life executing a power slide takes some practice, when you can do it it's gonna look easy, but watch videos of novices trying to learn, many stuggle and I've seen it myself at the tracks and autocross. It's not supposed to be as simple as GTS old physics make oversteering to be. You have to manage where the weight is over the tires to do oversteer on exits. I think many are feeling understeer on exit because unconsciously the old physics has taught them to respect throttle oversteer so much before. It served good to expose this to gamers. No longer in 1.39 is it that easy because in real life it isn't, otherwise people would be drifting spinning out left and right at high performance track days. Many want to and they mash the throttle and the car goes wide. The ones that I see usually spin happen on trail brake or tank spankers when they lift and get back on the throttle too suddenly. So many times at the tracks, people try to slide and they struggle they want to learn power oversteer because it does look cool, but many struggle even when coached. The drivers that are skilled at driving with oversteer exits make it look easier than it really is in real life. GTS old physics simplified this too much before 1.39 and allowed not much weight over the tires to matter as much as just throttle application to make the car rotate on exits. It was a mini game in throttle skill.
In real life the drivers that can exploit the cars nimbleness to navigate the courses are fastest in their class. Excessive oversteering is not fast, not to confuse .
