I used to walk to school at the age of what, 8? There was one really quite busy road I had to cross on my own, the rest was residential. But learning to cross the road is something that was dogmatically addressed from a very young age. "Stop. Look. Listen." I remember learning about that aged 5ish? My parents knew I could cross the road, they'd taught me, the schools had taught me. It was tested in the crucible of parental observation and then I was trusted to continue.
Of course someone could come along and kidnap me as I blithely wandered along the pavement. But frankly if we're going to spend our lives obsessing about extreme tail risks then we've already lost.
