I am curious, what step did she miss? According to the article, she looked back 2 times.
"As Willerton recalled, after looking behind her, she signaled, moved left into the traffic lane, signaled and looked again, and started her turn when Gray hit her as he tried to pass on the left."
I thought it a well written article and gives us some focal points when dealing with cycling accidents.
One is with law enforcement. When we are targeted or hit by a car, bit by a dog, etc... they are the ones that we need on our side.
Another is with the media. Call them out when they misreport a story or throw anti-cycling bias into a story.
And lastly, we need to pressure DAs to charge accidents with injuries and fatalities as serious matters.
