Jaywalker is a dumb term.

Dumb traffic rules were needed because of mostly Dumb zoning and land use at the heart of it all baked in in the 20s starting in our cities and spreading further and further outward well apart from but greatly enabling the huge car growth after   WW2. This growth hollowed out our cities and had their leaders mostly asking/ begging  for 90% funded highway links to their downtowns into the 60s. Even today many cities see value in their interstate links and are not looking to rip them out. The focus should be on states clawing back some of the zoning controls to get back to the density patterns that supported and made passenger rail profitable and would support growth of safe all age bike networks allowing cars to organically fall away.
