Has anyone on here dealt with a crash while on autopilot and how competing insurance companies decided fault? In my situation, I was in autopilot in the left lane going about 30 miles an hour in heavy traffic. In the lane on my right, an SUV pulling a long trailer attempted a lane change into my lane. When he got a few feet into my lane there was a collision before I had a chance to react to his encroachment. Luckily no one was hurt. The impact was to my passenger side bumper (not on the front of the bumper but only the side), front tire and there was a second impact near my rear wheel. His damage was to his passenger side front tire and inside of his front bumper. The other driver admits they were attempting a lane change but that I ran drizzly into them. My insurance company believes it is 100% his fault for entering my lane improperly when it was not clear and they say the evidence shows the other driver initiated the collision because all of the damage was to the side of my car and not the front. The other driver's insurance says it is 100% my fault for running directly into them while they were in my lane. Anyone have insight on how this could be decided? I am in a comparative fault state. It sounds like we will be going to arbitration. Also, does anyone think getting data from the EDR would help my case and should I spend $1000 on a Tesla EDR Retrieval Hardware Kit?
