Road Rage Fail

I don't know what caused her actions and only became aware of something when she swerved in front of me. Whatever happened was likely during my merging to surface street. No one was on my left as I merged so did not cut her off there. I included footage before the light to show that the drive was seemingly uneventful.

Edit: Three minutes before this clip...
