Perhaps one difference is that it seems to be considered good/normal parenting to expose your farm kids to mortal dangers, but it's definitely not considered good parenting to expose your city kids to mortal dangers (despite the city having no lack of mortal dangers).
I believe in the country, one chooses the dangers and has some control. In the city, the danger is mostly out of control.
Rural dangers are (usually) environmental/natural.
Urban dangers are other person.
A kid gets hurt hiking, "They were unlucky."
A kid on a scooter gets hit by a car, "Why weren't the parents watching?"
Rural values independence, Urban collectivism.
In the Urban situation you can emphasize with both kid and driver.
