Other countries are literally reducing road space that is exclusively for car use and building protected bike lanes and pedestrian spaces where such road users cannot be killed by cars.

The USA is likely not to the same degree. (Certainly not at the pace of Paris, which has changed remarkably)

This is the simple, dull solution. Cars inevitably kill other road users because they’re fundamentally unsafe. Remove cars from having any possible interaction with other road users and deaths go down. It’s that simple.
