Not your fault, she told her. Don't fret about it. These things happen. It is not the attitude that will keep crashes from happening. Most crashes are preventable.
Bikes broken in crashes are useless and expensive to repair or replace.
Broken bones are far worse. We have to educate the people who hold our physical safety in their hands, the people we follow, four inches back, while they think about, well, who knows what they think about. Everyone says education is key, communication is vital, but no one wants to say anything. No one learned a damn thing from that crash. There was no communication and no education.
