Here in Toronto Canada, while driving on a highway (The Gardiner heading into Downtown) - 8am rush hour - stop and go traffic. Essentially was in the absolute right lane in stop and go traffic, with vehicle in full autopilot control. I was watching the road and all, but I assumed the scenario under which the accident occurred would have been covered by Autopilot...learned the hard way it was not. Regardless, accident was "not at fault". What happened: I was driving in my lane, while another driver attempted to change lanes into my lane - Autopilot failed to pick up the other car entering and did not slow down - No beeps/warnings/etc. came on the dash board. Result: Driver side front hit of my X hit the passenger side rear of the other driver. When I got out to assess the damage, I saw "red paint" (other drivers car colour) on my front bumper, but I was able to wipe it right off with just my finger - Thank you XPEL! And could not note any other damage. I told the other guy I don't think theres any damage and it would be the cost of replacing the XPEL as far as I can tell. He starts accusing me and making it look like I was at fault and told me he'll go through insurance...so I told him fine be it. Took it to the Tesla Store and they confirmed, they don't think theres any damage under XPEL. Told the guy again its a couple hundred in repairs and it'll cost him an extra $1k or so in premium hikes if he wants to go through insurance...He insisted it was my fault and went....so, I called up the insurance co, and they said fault is always for the car entering the lane if the accident occurs while entering (which it did as it hit just as he started entering). Body shop assessed the damage after removing the XPEL and noted a couple minor scratches - "This could have been buffed out as long as I didn't have an issue with it - at most $20 Tesla paint touch up" - However they went ahead and repainted the front bumper fully. ~$800+taxes CAD ($588 USD) for parts and labour.
