best thing to do is move on and forget if it continues report it to police. In terms of giving enough space from what I saw of the video any closer to the curb on some of those passes you might riding through someones front garden. In terms of language personally if tend to use mouth first and think later its only understandable and humor nature.
Last and most important advice for a pro cyclist like yourself. My dad gave me this years ago.
Dont tie your shoe laces in revolving door.
