I'm starting to suspect someone screwed up and the blame is assigned backwards atm. In 1.15 I still get a full 10 sec penalty for someone brake checking me in the middle of a straight, it's the first clip in that compilation video I posted. A dive bomb hitting you in a corner gets a lower penalty then the victim taking the corner normally. Actually it doesn't look like it looks at incorrect braking at all. The game can race a bunch of AI cars together through corners, so it can determine correct entry speed for each car in a pack on the fly as well as determine the optimal line for each car. You would assume that the car deviating the most from the optimal solution is to blame when an incident happens. Of course the AI isn't very good and often brakes in the apex and tends to crash into you, so perhaps that's not a good idea.
