It also depends a lot on the local environment, time of day, day of year. And it doesn't sound like the kids even needed to cross a street. This parent didn't let their child run free: they stood out on the street and watched the kids on the "dangerous" part of their journey.
The biggest risk these days is that a busybody will call CPS, break up your family and traumatize your kids in foster care. Stop the fear-mongering.
My dad started teaching me C/C++ and basic electronics when I was 7-8, and I got my ham radio license when I was 9.
The idea that you need to be 12 to understand that you should run away from creepy strangers is hilarious and scary as fuck. These helicopter parents are dangerously kneecapping their kids right from the start :\
That said, I definitely have met some three year olds that would run directly into oncoming traffic without restraint, so I think this depends a lot on the specific kid.
In some countries, you need to drive you kid to school until they are 14.
I think a lot of people would argue that watching the kids until they’re practically in the door of the bakery constitutes a reasonable provision of safety and supervision.
As in you aren't even allowed to walk with them to school, you have to drive them in a car? Why's that?
