Nearly any actual that would result in fewer deaths is so far outside the Overton window.
Claiming that there are ineffective government agencies that pay attention to a few tiny aspects of safety but ignore the vast majority of them-better city designs-, is not a thug except window dressing to enable the neglect of these deaths.
You might find it risible to suggest that we are ignoring car deaths, but given the rise in car deaths and the lack of effective action against them, I find it far more risible to suggest that "we" are paying attention to them.
I've been paying attention to them since high school, when 0.5% of my high school died because of cars. Nobody did anything. Nobody suggested we enable life without cars. Nobody changed an intersection. Nobody suggested new technology. It was completely ignored. Sure, the kids were mourned, but we all ignored any action.
There is almost no way for a sober driver to kill a person and be deemed for their death. Police and highway patrol will just escort the driver off the scene. Kill a person crossing in a crosswalk with flashing lights? You'll walk away from the scene.
What other sort of danger do we allow around us? Much less mandate that a person must be exposed to cars if they want to be around other people? It's a preposterous situation that we have chosen and enforce by law. Until we realize what we are doing and acknowledge the car dependency to our legally required city planning, we will continue to ignore the costs that the law imposes on us.
Backup cameras are not going to save any significant amount of lives. What fraction of our car deaths are from backing up? Sure, it sounds like a good idea, and is a good idea, but it will not make the slightest dent in the death and carnage.
Lots of other cities in the US adopted "Vision Zero" policies after seeing how Osls was drastically reducing death. But US cities refuse to make any of the changes that are actually successful at reducing death.
Because what needs to change isn't just the design of the car, what really needs to happen is a change in the design of the road.
We must start designing cities with the assumption that drivers will make mistakes, as all people always do. The design of roads and intersections must minimize the change for a deadly mistake.
And perhaps, and here's the part that's really outside the Overton window, Pepe who want to travel by non-car means should have just as much access and safety as those inside cars. We force everyone in the US to get around by car if they are going to be the median participant in society. What if we had a world where the median person, with a job, was not expected to drive?
By all means, continue to advocate, but the idea that "we" ignore car crashes is risible.
