Survivorship bias. The rural kids riding their bikes all over the place who unfortunately got eliminated by cars didn't get to write hacker news posts. My own 6 year old has to cross a busy main road to get to school. Have I damaged him mentally by personally making sure he gets across twice a day, or have I mitigated the low risk of a catastrophic outcome?
