It seems like accepting riders 15 or at least 16+ would be a good compromise. At this age, they are actually either learning to or already driving themselves and eligible for an ID card to prove their age. It's probably safer than them driving themselves at this point (for them and those of us on the road!). I know many high-school kids who take public transit alone, so it would seem reasonable that they could handle a ride-sharing app. And, as someone pointed out, you can track their route and there is no cash involved, possible advantages over public transit.
