If you stay attentive when crossing, I think almost all crosswalks are safe. If you aren't attentive when crossing, none of them are safe.
Painted, unprotected lanes aren’t ideal, but they’re better than nothing if they encourage more people to cycle.
There’s plenty of examples where I live where painted cycle lanes have later been upgraded to proper protected cycle lanes (with kerbs, cycle-specific signals at intersections, etc) once they showed the demand was there.
I’d also argue that simply having more cyclists in an area makes cyclists safer because car drivers become more aware of them.
For rural roads a bike lane works fine as there are very few conflict points.
It really is. For decades, US fuel economy standards, emissions rules, and tax breaks and depreciation rules have all been weighted in favor of bigger, heavier vehicles.
The idea that "sharing the road" is possible if only we were all a little nicer and more attentive is a supremely naive fantasy that exists primarily as a justification to not build real physically divided infrastructure.
Painted bike lanes (and crosswalks, tbqh) are death traps and overall fucking terrible fig-leaf concepts. Barriers (and over/underpasses, etc) or nothing.
