Sadly, it's often not even a matter of safety from "danger", but safety from the law. Getting CPS called on you[1][2], or getting arrested[3][4] as a parent is not good, even if you are fortunate enough to win.
Then there's the whole angle of disappearing third places, lack of places that can be reasonably visited without driving privileges, nobody's outside because of all of the above so there's nobody to "hang out" or "play" with, desire to funnel kids/teens into more "productive" activities like academics and sports (depending on affluence and interest, this isn't AS bad as the above points), places outright banning[5] young people, etc etc.
