In most places I've lived, streets are objectively less dangerous than they were a few decades ago in all aspects except traffic density, which is a mixed bag. In places with poor urban design, I can see the argument that street (crossing, particular) is high risk for say 6-8 year olds. In places with better design, the idea that a 8 year old, let alone a 14 year old, shouldn't be able to navigate a reasonable distance by themselves seems pretty crazy.
