My eldest is also a daughter of a similar age. What my partner and I have said is "yes you're old enough to go do things, as long as you're going with friends." She's not old enough to go places alone, or to go places where she'll be supervising her younger sibs. But she's old enough to be in a setting where peers are watching out for each other and know how to find help if needed. I know that's still a walk-back from what previous generations enjoyed, but it's not that different from what we both experienced at this age in the 90s. And in parallel to this, we've put a fair bit into teaching our kids to navigate on foot, use public transportation, and safely ride their bikes on the road— all of it an investment in pre-car/non-car teenage autonomy.
