AFAIK, what they aim for (and often do) in the Netherlands is what I said: having all houses in 30km/hour zones and requiring any crossings of higher-speed car lanes to be on segregated cycle paths. Kids don’t walk their bike to a cycle path or cycle on the sidewalk to avoid cars, they enter the street in front of their house (likely after riding on the sidewalk for a few meters, even though that’s illegal. Adults do that, too) That street either has a low speed limit or has separated cycle paths.
