it is hard to tell the scenario 2 is so clear, i ams in some cars too braking earlier to have better exit, for example Mazda 787  , so the car in rear ust coint this too but there are nearly all try to overtake ASAP as they aproach you without read your style firstly

This problem can be mitigated if some app in server stores the braking points for each turn and analyse like an median point to check if the braking point was a brake test or not, or using some anomaly detection algorithms like Cluster Analysis, pondered to the number of laps and amount of fuel in case of tyre degradation. Depending on the distance from the cluster, it can be named as an abnormal point that can be used to make someone who touch the rear end guilty or not.
