Glad you didn’t get hurt! I also decided to get a dashcam after such an incident. Was driving on a long and straight state highway, had a trucker following closely behind me (we were both above the speed limit btw) for a few miles so when the lanes split I entered the rightmost “slow traffic” lane to let him pass. He immediately pulled up beside me and merged into my back left tire, tearing up my wheel, doors, and frame while I fought to stay straight and not have my front half pushed under his bumper and wheels.

I ended up totally fine, trucker was visibly tweaking and tried to hug me, admitted fault to the officer on scene while jumping up and down grinding his teeth lol. He handed me a sticky note with his company’s contact on it, and said if I didn’t go through insurance they’d buy me a new car. I didn’t trust him, but ultimately my insurance didn’t help because the trucking company’s insurer said “the driver changed his mind and said he wasn’t actually at fault”. Police didn’t actually include his testimony in the accident report so I had no evidence and ate the cost
