Without context, this video posted to YouTube on Friday remains a curious non sequitur: an enraged man repeatedly bashes a 30 Stockton Muni bus while yelling such threats as "I'll fucking kill you." (Yes, there is loud profanity, so if you are in mixed company please don headphones.)

What do you think the bus could have done to deserve such ire? I mean, it's the 30! Not the 14 or the N, for both of which such rage can be understandable. Then again, I haven't ridden the 30 for a while, maybe it's gotten more frustrating in the interim? Any speculation (informed or otherwise) is welcomed in the comments.
