One thing we can do is to stop referring to these as "accidents" and call them what they are: negligence by motor vehicle operators.
And demand that the news media and law enforcement do the same. Or, at a minimum, use specific wording when a driver collides with a cyclist, rather than implying nobody was at fault. And stop implying victim blaming by including the obligatory comment about whether the cyclist was wearing a helmet.
Until the US changes the paradigm, nothing else will change. It's getting worse, and we haven't seen the worst of it yet.
