"Oh shot their not going to stop" is a pretty traumatic young to realize, it kicks you into fight or flight mode. Like you said, you can't fix stupid, and you can't start a physical fight over it, which leaves flight. We're just primed that way. You said you regret leaving, no one can blame you. With no injury and no damage to the bike you wouldn't have been able to get a lawyer to work on contingency.
Glad you and the bike are ok.
