The streets between home and the supermarket are very quiet. They are quite narrow and there are speed humps and other traffic-slowing structures along the way. Child abductions by strangers are vanishingly rare. Miro was just in violation of the limits as to how far he was allowed to venture from home but in no actual danger. My daughter and all her school mates used to walk home a distance longer than between @gamer00's home and the supermarket unaccompanied by an adult from school every day in first grade. The city of Lahti has top-notch street infrastructure. For instance, there are plenty of underpasses along every major street or road with busy traffic.
