In that situation I’m concerned about other drivers, and also the child not paying attention while staring at their phone. I have seen sooo many teens just step off the curb and walk across the street without even looking up from their phone. Stranger Danger would have nothing to do with it.
There needs to be a better balance between the latch key kid independence/responsibility and the absolute lack of trust in your kids and your community to just not be child kidnapping murderers???
