Likwise in source 4 some Children don't get their driver license its not because they're lazy it's because they don't need them, yeah they come in handy but they're not interseted for example in source 4 they stated "They organized their summer jobs and socail life around where they can walk or take public ransportation or car-pool with friends." having a car isn't a teenager main interst, they rather walk to a close by place or car pool with their friends.
