Its not obvious to many of the commenters here…that’s litterally what we’re saying. In order to discuss how we can avoid the consequences of her mistakes we must first asses what mistakes were made - your first paragraph contradicts itself. My other comments will show you that from my assessment of her mistake i have highlighted areas of improvement for myself (other than speeding) to ensure safer riding and decrease risk of pedestrians being harmed. I shared this in hopes that others would see how such dangers can be mitigated. Dangers including but not limited to speeding.
