Never going to risk my life commuting by bike in NYC. Dont push your lifestyle onto me. Or in the vernacular, “You do you.” I’ll stick with the subway.
There'd be less opportunity for fatal crashes due to the surface area between cycle paths and car paths being reduced. This would literally mean that it'd be safer if there was better infrastructure.
Proper bike infrastructure isn't just extra lanes next to cars. Typically "proper" includes things like protective walls, and bridges specifically for bikes + pedestrians separate from cars.
It is entirely possible to design bike infrastructure that removes car impacts from the equation - we have the technology, we only lack the political will.
Proper bike infrastructure is for example a line of trees between a cycling path and a road. Or a moat with water and angry homeless drug addicted goose. Reading the comments here makes me think drug addicts in the streets work quite well as urban planning tool is US.
