I don't know if you're referencing the incident at 2:26 or 3:37, but in both of those situations you're actually being penalized for wall contact or going off track. That red outfield you went on in turn 1 (and in several other areas of the track) has gotten me several penalties, as well as getting a little too reliant on the curbing. As for 3:37, you took several liberties with the track limits at 3:28 and onwards - I was taking time penalties for track cutting just in qualifying for cuts similar to yours at 3:30, and at 3:35 it looks like you even clipped the inner wall, which by default would be an instant SR penalty for the sector.
Even if that wasn't the case you should've had your eyes looking a little further ahead, that Hyundai hit the inner wall at about 3:34 and was forced outwards. You had the opportunity to let off the gas or brake, but you were on the accelerator right up to the point that you slammed into him. I think it would've been fair to give both of you a penalty for that incident.
Either way, the entire SR system is far too heavily weighted on track boundary infringements - honestly I don't think I've been penalized for vehicle-vehicle contact more than three or four times, and I've given out and received some pretty hefty shunts.
