It’s effectively an impossibility to do it differently – kids have to walk to school, and have to take bike or public transit at age 10 to secondary school – often biking 20km in one direction, or using the bus halfway across the city.<p>Parents can’t afford to waste time (or money) taking their kids to school when those can go to school perfectly safe anyway.<p>So it makes sense that children age 10 would be able to use the bus and go into the city and buy stuff themselves.
