Yes, and consider the "kids having a semblance of independence" rate in the 40's too.
100 kids walk to school, drivers kill 5 of them.
Situation B:
98 kids are driven to school (because walking is dangerous!) 2 kids walk to school, drivers kill 1 of them.
Which is safer?
I think you messed up your analysis somewhere. LOL
It’s not hard to understand.
The purpose was to show the effects that car over-reliance has on public safety and quality of life.
In the second scenario, everyone thinks the roads are too dangerous for kids (becuase they are, as evidenced by half of them getting killed) so they all drive their kids to school in oversized heavy vehicles making the roads even more dangerous.
