"Cities make it easier for kids to go outside and be kids."
The other way round.
I grew up in the countryside and we could literally play on the streets without risk. Visiting friends was actually easier. We simply took the bike, the rollerskates or - later - a motor scooter. No need for any parent to drive anybody anywhere. No need to use public transportation. All my schoolmates lived in bike distance (that is 25 km in my definition).
Of course it counts how safe your country or city is. It is our business to make them safe, not to hide in cars, because otherwise we may be harmed.
