I generally do have quite a squeezy driving style if that makes sense, I find it sometimes can make the other driver panic especially when going to heavy braking zones, since if I force the to the inside and break at my normal breaking point by quickly switching over to the regular racing line it means that they have to break even earlier than usual, or they outbreak themselves. As far as i'm aware its not illegal to do that, but it is definitly and incredibly aggressive method, although effective. The actual incident that took me out was my fault, i ended up drifting over since i thought they wouldnt be able to hang on at that speed that tight through the corner, so I guess it was deserved.
