Yes you can fix this. The Dutch bicycle culture was started by municipal votes, where resolutions passed municipal governments with margins of single votes. If American politicians can pull their heads out of their asses and even only pass a resolution that:
Disseminates empirical research on road safety to all traffic engineers,
Prioritises safety for all users on roads and streets, with priority given to those without armour (i.e. a car), and maybe
Penalised engineers and politicians who choose to fail to design for safety
Then in the next thirty odd years, I think that the worst offenders can be rebuilt.
Do note that few things are as good at destroying themselves in regular, correct use as car infrastructure.
