This theory was brought up and discussed in a previous similar incident. Here is the question / answer detailing that in the comments of that previous YouTube video:
Question: The only thing I can think of is that you were too close to the lane on the right. If you were using the autopilot, it usually is. When I split the lanes, most Tesla cars are close to the split lane and it’s hard to pass you. Or, as someone once said, you’ve met this guy before. Did you grab his license plate?
Reply: I tested this autopilot theory, and I think you are right, and no the camera could not get the license plate, it was not clear, it happened so fast before that i could realize what had happened it was far away but thanks now i know what happened.
This is just a reminder to note that autopilot can make you look like a pilot hugging the line, so beware.
This new video was recorded in Los Angeles where lane sharing is legal. The video description simply says:
My Tesla Model 3 is deliberately hit by a guy on a motorcycle. It happened in Los Angeles on the 105 eastbound around 7 a.m. on 7/31/20. Not provoked.
